use git source for python-troveclient in functional dsvm datastore

The trove-functional-dsvm-{datastore} tests gets the troveclient
from pypi.
This causes trouble with our 'root disable' feature that hasn't
been released in a official build yet.

Pull the troveclient bits from git so that we're always integration
testing the newest stuff.
