Resolve the following RemovedIn20Warning warning:
"ApplicationCredentialRoleModel" object is being merged into a Session
along the backref cascade path for relationship
"ApplicationCredentialModel.roles"; in SQLAlchemy 2.0, this reverse
cascade will not take place. Set cascade_backrefs to False in either
the relationship() or backref() function for the 2.0 behavior; or to
set globally for the whole Session, set the future=True flag
This also applies for "ApplicationCredentialAccessRuleModel" and
"AccessRuleModel.application_credential".
