Matt Riedemann dcde535f95 Handle None returned from get_allocation_candidates due to connect failure 
The get_allocation_candidates method is decorated with the safe_connect
decorator that handles any failures trying to connect to the Placement
service. If keystoneauth raises an exception, safe_connect will log it
and return None. The select_destinations() method in the SchedulerManager
needs to handle the None case so it doesn't assume a tuple is coming back
which would result in a TypeError.
