Code Issues Proposed changes

Deprecate [glance]api_servers 

When adding support for standard ksa config options in Queens [1], we
retained the [glance]api_servers option in case consumers wanted to
continue to rely on nova's rudimentary load balancing rather than
implementing something real. Continuing to support this option is
holding us back from the things that having a common standard across
services would facilitate, like using openstacksdk rather than clients.
So deprecate it.

deprecations:
- |
The ``[glance]api_servers`` configuration option is deprecated and will be
removed in a future release. Deployments should use standard keystoneauth1
options to configure communication with a single image service endpoint.
Any load balancing or high availability requirements should be satisfied
outside of nova.
