Pass source VM UUID (if known) to backend

Browse Source 
Some backends (not yet implemented) which talk to management
layers will have mappings for what VMs can control what other
VMs.  So, the source VM UUID of the original request needs to
be sent along with the target VM UUID to the management layer
for arbitration.
