Unlike cinderclient, SDK attempts to connect to a service as soon as you
create a client. A keystoneauth1.exceptions.catalog.EndpointNotFound
exception can be raised if this service does not exist in the service
catalog. Avoid this for the quota and limits commands by first checking
if the service is enabled.
In the process, we rework the 'is_volume_endpoint_enabled' helper we are
using to check for the existence of the service to *not* require a
volume client, since this was causing a chicken and egg issue for us
(and was also pretty much unnecessary).
