data_platform_libs.v0.database_requires was deprecated on January 4th, 2023 and has not received updates since then. This change migrates to data_platform_libs.v0.data_interfaces which the preferred way to interact with MySQL. Most notable changes: - User/password in a secret - Keystone test 'test_on_peer_data_changed_with_fernet_keys_and_fernet_secret_different' is no longer mocking secrets to make sure it's using database secrets.
