Remove cinder's "volume" (API v1) service from the keystone catalog.
This fixes a post-FFU bug that causes keystone endpoint validation to
fail. Cinder stopped supporting its v1 API in queens, but tripleo
retained the "volume" service (with API v3 endpoints) to work around
a bug in the version of tempest used in queens (see [1] for details).
The endpoint validation fails because the "volume" and "volume3" servces
share the same v3 endpoints.

The patch was tested locally:
- Confirm a fresh deployment (with patch) succeeds
- Manually create "volume" service with "cinderv3" endpoints. This
replicates the post-FFU scenario
- Perform a stack update (succeeds), and confirm the "volume" service
has been deleted
Final note: The ansible task that removes the "volume" service is a
deployment (not upgrade) task. This ensures the service is removed from
overcloud deployments that already performed the FFU.
