core: hosted-engine: Lock the sd import exclusively

Add an exclusive lock on the hosted engine domain import to prevent it
from interleaving. There is a race where the domain might be added but
the TX isn't closed yet and another import can enter and pass the
command validation.

Small clean-up made to remove the redundant getBackend() and
 runVdsCommand(..)  methods.
