Remove oauth provider (#15666)

* Remove oauth provider

This removes the oauth provider functionality from awx. The
oauth2_provider app and all references to it have been removed.
Migrations to delete the two tables that locally overwrote
oauth2_provider tables are included. This change does not include
migrations to delete the tables provided by the oauth2_provider app.

Also not included here are changes to awxkit, awx_collection or the ui.

* Fix linters

* Update migrations after rebase

* Update collection tests for auth changes

The changes in https://github.com/ansible/awx/pull/15554 will cause a
few collection tests to fail, depending on what the test configuration
is. This changes the tests to look for a specific warning rather than
counting the number of warnings emitted.

* Update migration

* Removed unused oauth_scopes references
