This adds the Cheesecake Replication implementation
for the SolidFire driver.
We add the necessary methods for creating a replicated volume and
performing a failover properly that updates the status of volumes
on the failover host.
We also make sure that things like delete, attach etc work in a
failed over scenario.
For SolidFire we are using the remote cluster mvip as the
backend_id, here's an example replication_device entry for
a cinder.conf:
replication_device =
backend_id:192.168.139.102,mvip:192.168.139.102,login:admin,password:admin
Note that there's an independent fix from this patch series that needs
to be applied in order for things to work properly:

The last remaining task is to ensure we detect and deal with a restart
when we're in a failed over state.
