Eric Fried 0a8f019be0 nova.utils.get_ksa_adapter()
Provide a new method:

nova.utils.get_ksa_adapter(service_type, ks_auth=None, ks_session=None,
                           min_version=None, max_version=None))

...to configure a keystoneauth1 Adapter for a service.  The Adapter, and
its component keystoneauth1 artifacts not passed into the method, are
loaded based on options in the conf group corresponding to the specified
service_type.

The ultimate goal is to replace the various disparate mechanisms used by
different services to do endpoint URL and version discovery.  In Queens,
the original mechanisms will still take precedence, but (other than
[glance]api_servers - see the spec) will be deprecated.  In Rocky, the
deprecated options will be removed.

This change incorporates the above utility into endpoint discovery for
glance and ironic.  Future change sets will do the same for other
services (cinder, neutron, placement).

upgrade:
- |
Nova now uses keystoneauth1 configuration to set up communication with the
baremetal service. Use keystoneauth1 loading parameters for auth, Session,
and Adapter setup in the ``[ironic]`` conf section. This includes using
``endpoint_override`` in favor of ``api_endpoint``.
deprecations:
- |
Configuration option ``[ironic]api_endpoint`` is deprecated in favor of
``[ironic]endpoint_override``.
