Code Issues Proposed changes

Add debug logs when doubling-up allocations during scheduling 

During claim_resources in the scheduler, if the consumer (instance)
has existing allocations, the scheduler thinks we're doing something
like a resize to same host or evacuation, but it would be useful
to know what the original allocations when doing that, so this adds
logging of the original allocations that take us down the double-up
path.
