Configure nova_cell1.conf to use placement for reschedules

Browse Source 
Nova now calculates alternate hosts in the scheduler and
sends those to the cell for reschedules in case a build on
a given compute node fails.

The cell conductor needs to claim resources against the
alternate hosts in Placement during a reschedule, therefore
it needs to be configured to talk to the placement service.

Part of blueprint return-alternate-hosts
