This change fixes up a few things in the SolidFire driver to enable the ability to "fail back" to the original cluster in a replication scenario. We're still assuming a cluster-wide fail over, but now an admin has the ability to specify subsequent `cinder failover-host` calls to switch back and forth between their SF clusters. This change promotes the target on a fail over and also now attempts to set up replication back to the original src as well (assuming the original is available and not a puddle of melted goo). This means that writes to the new back end will be replicated back to the src, so if a user so chooses they can fail back to the original and have their new data.
