The attribute methods for a model are currently defined lazily the first
time that model is instantiated, even when `config.eager_load` is true.
This means the first request to use each model incurs the cost, which
usually involves a database round trip to fetch the schema definition.
By defining the attribute methods for all models while the application
is booting, we move that work out of any individual request. When using
a forking web server, this also reduces the number of times the schema
definition is queried by doing it once in the parent process instead of
from each forked process during their first request.

Before this change this test was passing even if we revert #31135. The
reason for that is that `app 'development'` will load the environment in
the test process and it is happening before db_create_and_drop is
called.
This was not asserting that the environment was loaded in the db:create
task itself.
To test it we enhance the db:create task with a block that writes to a
tmp file the value of the config. If the environment is loaded before
that task enhancement runs the content of the file will have "true"
insteand of "false".

does not support it
If you are using the "in cache versioning" also known as "recyclable cache keys" the cache store must be aware of this scheme, otherwise you will generate cache entries that never invalidate.
This PR adds a check to the initialization process to ensure that if recyclable cache keys are being used via
```
config.active_record.cache_versioning = true
```
Then the cache store needs to show that it supports this versioning scheme. Cache stores can let Rails know that they support this scheme by adding a method `supports_in_cache_versioning?` and returning true.

For `production` environment look first for `config/credentials/production.yml.enc` file that can be decrypted by
`ENV["RAILS_MASTER_KEY"]` or `config/credentials/production.key` master key.
Edit given environment credentials file by command `rails credentials:edit --environment production`.
Default behavior can be overwritten by setting `config.credentials.content_path` and `config.credentials.key_path`.

In production the query cache was already being loaded before the first
request even without #33856, so added a test to make sure of it.

It would allow `filter_attributes` to be reused across multiple
calls to `#inspect` or `#pretty_print`.
- Add `require "set"`
- Remove `filter_attributes` instance reader. I think there is no need
to keep it.

In a test app we observed that the query cache was not enabled on the
first request. This was because the query cache hooks are installed on
load and active record is loaded in the middle of the first request.
If we remove the `on_load` from the railtie the query cache hooks will
be installed before the first request, allowing the cache to be enabled
on that first request.
This is ok because query cache doesn't load anything else, only itself
so we're not eager loading all of active record before the first
request, just the query cache hooks.

sensitive value of database column when call `#inspect`
* Why
Some sensitive data will be exposed in log accidentally by calling `#inspect`, e.g.
```ruby
@account = Account.find params[:id]
payload = { account: @account }
logger.info "payload will be #{ payload }"
```
All the information of `@account` will be exposed in log.
* Solution
Add a class attribute filter_attributes to specify which values of columns shouldn't be exposed.
This attribute equals to `Rails.application.config.filter_parameters` by default.
```ruby
Rails.application.config.filter_parameters += [:credit_card_number]
Account.last.insepct # => #<Account id: 123, credit_card_number: [FILTERED] ...>
```

`spec` is the same variable name as gemspec generated by bundler, and its
intention is easier to understand than a one-letter variable.

This is follow up on 1c59b4840c58097186022f68427c46e0046c5d0d. `spec` is already in use there.

The rake tasks which became deprecate now does not load the environment.
Therefore, even if the application specifies the behavior of deprecating,
the message is output to stderr ignoring the specification.
It seems that this is not the expected behavior.
We should respect the setting even in the rake tasks.

Part 3: Multi-db Improvements, identifying replica configurations

Changes the `configs_for` method from using traditional arguments to
using kwargs. This is so I can add the `include_replicas` kwarg without
having to always include `env_name` and `spec_name` in the method call.
`include_replicas` defaults to false because everywhere internally in
Rails we don't want replicas. `configs_for` is for iterating over
configurations to create / run rake tasks, so we really don't ever need
replicas in that case.

Now the default is `:random`, and since the tests added with it are
removed. That config is unnecessary.

While the three-tier config makes it easier to define databases for
multiple database applications, it quickly became clear to offer full
support for multiple databases we need to change the way the connections
hash was handled.
A three-tier config means that when Rails needed to choose a default
configuration (in the case a user doesn't ask for a specific
configuration) it wasn't clear to Rails which the default was. I
[bandaid fixed this so the rake tasks could work](#32271) but that fix
wasn't correct because it actually doubled up the configuration hashes.
Instead of attemping to manipulate the hashes @tenderlove and I decided
that it made more sense if we converted the hashes to objects so we can
easily ask those object questions. In a three tier config like this:
```
development:
primary:
database: "my_primary_db"
animals:
database; "my_animals_db"
```
We end up with an object like this:
```
@configurations=[
#<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10
@env_name="development",@spec_name="primary",
@config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>,
#<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90
@env_name="development",@spec_name="animals",
@config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>
]>
```
The configurations setter takes the database configuration set by your
application and turns them into an
`ActiveRecord::DatabaseConfigurations` object that has one getter -
`@configurations` which is an array of all the database objects.
The configurations getter returns this object by default since it acts
like a hash in most of the cases we need. For example if you need to
access the default `development` database we can simply request it as we
did before:
```
ActiveRecord::Base.configurations["development"]
```
This will return primary development database configuration hash:
```
{ "database" => "my_primary_db" }
```
Internally all of Active Record has been converted to use the new
objects. I've built this to be backwards compatible but allow for
accessing the hash if needed for a deprecation period. To get the
original hash instead of the object you can either add `to_h` on the
configurations call or pass `legacy: true` to `configurations.
```
ActiveRecord::Base.configurations.to_h
=> { "development => { "database" => "my_primary_db" } }
ActiveRecord::Base.configurations(legacy: true)
=> { "development => { "database" => "my_primary_db" } }
```
The new configurations object allows us to iterate over the Active
Record configurations without losing the known environment or
specification name for that configuration. You can also select all the
configs for an env or env and spec. With this we can always ask
any object what environment it belongs to:
```
db_configs = ActiveRecord::Base.configurations.configurations_for("development")
=> #<ActiveRecord::DatabaseConfigurations:0x00007fd1acbdf800
@configurations=[
#<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10
@env_name="development",@spec_name="primary",
@config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>,
#<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90
@env_name="development",@spec_name="animals",
@config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>
]>
db_config.env_name
=> "development"
db_config.spec_name
=> "primary"
db_config.config
=> { "adapter"=>"sqlite3", "database"=>"db/development.sqlite3" }
```
The configurations object is more flexible than the configurations hash
and will allow us to build on top of the connection management in order
to add support for primary/replica connections, sharding, and
constructing queries for associations that live in multiple databases.

Issue #27852 reports that when `rails db:create` fails, it causes
leaking of user's DB credentials to $stderr.
We print a DB's configuration hash in order to help users more quickly
to figure out what could be wrong with his configuration.
This commit changes message from
"Couldn't create database for #{configuration.inspect}" to
"Couldn't create '#{configuration['database']}' database. Please check your configuration.".
There are two PRs that fixing it #27878, #27879, but they need a bit more work.
I decided help to finish this and added Author of those PRs credit in this commit.
Since it is a security issue, I think we should backport it to
`5-2-stable`, and `5-1-stable`.
Guided by https://edgeguides.rubyonrails.org/maintenance_policy.html#security-issues
Fixes #27852
Closes #27879

We originally did the whole `load_database_yaml` thing because this test
wasn't cooperating and we needed to finish the namespaced rake tasks for
multiple databases.
However, it turns out that YAML can't eval ERB if you don't tell it it's
ERB so you get Pysch parse errors if you're using multi-line ERB or
ERB with conditionals. It's a hot mess.
After trying a few things and thinking it over we decided that it wasn't
worth bandaiding over, the test needed to be improved. The test was
added in #31135 to test that the env is loaded in these tasks. But it
was blowing up because we were trying to read a database name out of the
configuration - however that's not the purpose of this change. We want
to read environment files in the rake tasks, but not in the config
file.
In this PR we changed the test to test what the PR was actually fixing.
We've also deleted the `load_database_yaml` because it caused more
problems than it was worth. This should fix the issues described in
https://github.com/rails/rails/pull/32274#issuecomment-384161057. We
also had these problems at GitHub.

In the system test template, enter a value based on label.
However, since `label` method does not use `titleize` by default.
If generate a value including underscore, cannot find a label and the test
will fail.
```
$ ./bin/rails g scaffold user name:string phone_number:string
$ ./bin/rails t test/system/users_test.rb
E
Error:
UsersTest#test_creating_a_User:
