427464f664 Support cinder-volume running active-active
Add the ability to run the cinder-volume service in an active-active
configuration. This involves two settings:

1) Configure the service's cluster name. This is the signal to the
   cinder-volume service that it should run in active-active mode.

2) Configure the "backend URL" cinder uses for its distributed lock
   manager (DLM). This patch assumes that DLM is etcd3, and it's
   accessible via an HTTP gateway.
