AWX Collections for DAB RBAC

Adds new modules for CRUD operations on the
following endpoints:

- api/v2/role_definitions
- api/v2/role_user_assignments
- api/v2/role_team_assignments

Note: assignment is Create or Delete only

Additional changes:
- Currently DAB endpoints do not have "type"
field on the resource list items. So this modifies
the create_or_update_if_needed to allow manually
specifying item type.
