Public bug reported:

On initializing the token_api due to the way the dependency injector
works, an infinite recursion occurs at:

https://github.com/openstack/keystone/blob/1af24284bdc093dae4f027ade2ddb29656b676f0/keystone/token/persistence/core.py#L228-L236

This occurs when doing the lookup for token_provider_api causes an
issue. The solution simply requires verifying that the 'item' is not in
self._dependencies or self._optionals.


This stabilizes eventually after startup.
