* ActiveRecord::ConnectionTimeoutError - could not obtain a database
connection within 5 seconds. The max pool size is currently 5;
consider increasing it:
Modified version:
* ActiveRecord::ConnectionTimeoutError - could not obtain a database
connection within 5.000 seconds (waited 5.000 seconds)

This change allows to instantiate all ActiveRecordError descendant
execption classes without arguments, which might be useful in testing
and is far less surprising than mandatory arguments.

These 3 methods expect `ConnectionAdapters` to have `tables` method,
so make it clear that `tables` method is interface.
* `ConnectionAdapters::SchemaCache#prepare_tables`
* `db:schema:cache:dump` task
* `SchemaDumper#tables`

Basically view tests for MySQL are same with
`test/cases/adapters/postgresql/view_test.rb`.
So move `test/cases/adapters/postgresql/view_test.rb` to
`test/cases/view_test.rb` and make them only run if
`current_adapter` supports writable view.

test runner sets file to be tested in plugin_rails_options,
but in plugin_rails_options, processing has been made to the argument of the
actual command rather than the argument of Minitest.run.
For example, if you run `./bin rake db:migrate test`, the options[:patterns], `db:migrate test` was incorrectly set.

test runner
Currently, if a file or directory that does not exist was specified in the test runner,
that argument is ignored.
This commit has been modified to cause an error if there is no file or directory.

SSL redirect:
* Move `:host` and `:port` options within `redirect: { … }`. Deprecate.
* Introduce `:status` and `:body` to customize the redirect response.
The 301 permanent default makes it difficult to test the redirect and
back out of it since browsers remember the 301. Test with a 302 or 307
instead, then switch to 301 once you're confident that all is well.
HTTP Strict Transport Security (HSTS):
* Shorter max-age. Shorten the default max-age from 1 year to 180 days,
the low end for https://www.ssllabs.com/ssltest/ grading and greater
than the 18-week minimum to qualify for browser preload lists.
* Disabling HSTS. Setting `hsts: false` now sets `hsts: { expires: 0 }`
instead of omitting the header. Omitting does nothing to disable HSTS
since browsers hang on to your previous settings until they expire.
Sending `{ hsts: { expires: 0 }}` flushes out old browser settings and
actually disables HSTS:
http://tools.ietf.org/html/rfc6797#section-6.1.1
* HSTS Preload. Introduce `preload: true` to set the `preload` flag,
indicating that your site may be included in browser preload lists,
including Chrome, Firefox, Safari, IE11, and Edge. Submit your site:
https://hstspreload.appspot.com
