Unity Driver v0.5.1: Add Unity thin clone support for Newton

Unity storage now supports cloning volume by taking its snapshot,
it's more efficient than previous implementation.

However, there is limitation on the count of thin clones inside one LUN
family sharing the same base LUN. Every time the limitation reaches, a
new volume will be cloned using dd copy. Then thin clone will be taken
from the new dd-copied volume.
