This patch does multiple things regarding auth_* parameters.
1/ We deprecate auth_host, auth_url, auth_port and auth_protocol
If they are set, a nice warning will show up and mention the parameters
will be dropped in a future release. The parameters are still having
effect but will configure old parameters. No worries, they still work.
Just lot of warnings so people will have to use new parameters.
2/ Add new parameters
auth_uri and identity_uri are the way to go!
False by default for now, because we still have old parameters, but in a
later release, they'll be set to a default endpoint, like in other
modules.
3/ Update beaker
We want to test with the new parameters, so let's update beaker
manifests and use auth_uri & identity_uri
This is a first step to use auth_uri & identity_uri that is compliant
with other modules. The next step will be to drop old parameters and set
the right default values for the 2 new params.
