Alan Bishop 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.

Add the ability to configure the cinder-volume service to run in
active-active mode using the specified cluster name. Note that
active-active mode requires the etcd service be enabled, as it's used by
the cinder-volume service for its Distributed Lock Manager (DLM).
