Rather than a lot of checks use a switch statement. This optimizes the

Implement the secure way to transport non-shared storage data across

The capability also represents that 'blockdev-add' is functional. It's
necessary to detect it via presence of 'blockdev-del' since blockdev-add
did not have the unsupported 'x-blockdev-add' version previously and
thus would be marked as present even if we could not use it.

The initiation of a synchronous block job in the NBD storage migration
code was placed after entering the monitor thus after the lock on the VM
object was unlocked. Thankfully nothing bad could happen in this
situation since the migration job prevents any disk detaches or other
modifications of the domain object.
