Finalize migration to keystoneauth adapters
removes code that allowed some service sections to not have and use keystoneauth adapter options. Also deprecates `[keystone]region_name` option in favor of per-client option of the same name. Change-Id: Ifd58947b016bfa93b516dd47a170ba8f5abf277e Closes-Bug: #1699547

Configure the ironic-conductor service to use specific Image service

|

.. code-block:: ini

[glance]

Set a specific URL (replace ``NETWORKING_SERVICE_ENDPOINT``)
|

for connecting to the Networking service, to be the Networking
|

service endpoint - only for the case when you do not want to use

discovery of Networking service endpoint from keystone service catalog:

By default, in order to communicate with another service, the Bare

Metal service will attempt to discover an appropriate endpoint for
|

that service via the Identity service's service catalog.
|
||||
The relevant configuration options from that service group in the Bare
|
||||
Metal service configuration file are used for this purpose.
|
||||
If you want to use a different endpoint for a particular service,
|
||||
specify this via the ``endpoint_override`` configuration option of
|

that service group, in the Bare Metal service's configuration file.

for security reasons).

Replace ``IRONIC_API_IP`` with IP of specific ironic-api service as follows:
|

|

.. code-block:: ini

[conductor]

# URL of Ironic API service. If not set ironic can get the

endpoint_override=http://IRONIC_API_IP:6385

Networking service endpoint.)
