* Allow association's `foreign_key` to be composite
`query_constraints` option was the only way to configure a composite foreign key by passing an `Array`.
Now it's possible to pass an Array value as `foreign_key` to achieve the same behavior of an association.
*Nikita Vasilevsky*
* Allow association's `primary_key` to be composite
Association's `primary_key` can be composite when derived from associated model `primary_key` or `query_constraints`.
Now it's possible to explicitly set it as composite on the association.
*Nikita Vasilevsky*
* Add `config.active_record.permanent_connection_checkout` setting.
Controls whether `ActiveRecord::Base.connection` raises an error, emits a deprecation warning, or neither.
