Don't throw exception while defining new VM
...
This would throw an exception since we tried to find the current host of
a VM that did not exist yet. If this happens, just get None.

Implemented coordinated locked node transitions
...
The previous method was a "throw it in the sea"-type migration with some
(very arbitrary) sleep statements thrown in for good measure.
Reimplement this with some hard locking. During each phase of the
transition, the nodes acquire read/write shared locks to a Zookeeper key
so that they can tightly coordinate the actions of transferring each
part of the primary state between them. This is done in a subthread to
prevent strange blocking issues that were encountered, likely due to
business in the existing main thread.
