Add replica? check to DatabaseConfig

Checks if the config has a "replica" key, if so the configuration is for
a replica database. This is useful for excluding replicas from the
configurations list when creating the rake tasks or running rake tasks.
For example, we don't want to create the primary and primary_readonly.
They're the same database.
