This cleans up some dead code for handling Cinder volumes for drivers
that have been removed. The impacted drivers are:
Removed in Ocata
* AOE (CORAID)
Removed in Stein
* DRDB
* HGST
* ITRI DISCO
Removed in Train
* Veritas Hyperscale
Removed in Ussuri
* Sheepdog - the project has been defunct for several
years now and was considered dead code in Cinder
Since these drivers are not useful without Cinder, they are considered
dead code and therefore do not need to go through a deprecation period
in Nova.
