This bug is not valid.  The task needs to run periodically to expire any
reservations that should be expired ahead of QUOTAS.reserve() calls.
The only alternative is to expire reservations explicitly before every
single QUOTAS.reserve()... which is not as performant.

This task doesn't necessarily belong in nova-scheduler.  It really could
easily be moved to nova-conductor or nova-compute or something... but it
needs to run somewhere!

Title:
  SchedulerManager._expire_reservations doesn't need to always be
  running

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  The nova-scheduler log is filled with:

  2013-08-13 23:30:56.219 730 DEBUG nova.openstack.common.loopingcall [-] Dynamic looping call sleeping for 60.00 seconds _inner /opt/stack/nova/nova/openstack/common/loopingcall.py:132
  2013-08-13 23:31:56.228 730 DEBUG nova.openstack.common.periodic_task [-] Running periodic task SchedulerManager._expire_reservations run_periodic_tasks /opt/stack/nova/nova/openstack/common/periodic_task.py:176

  This periodic task is to help the quota system work, but if the
  scheduler hasn't done anything for the past few minutes there is no
  reason to keep running this task.  Instead it can be restarted upon
  the next scheduling event.

  The main benefit from fixing this will be cleaner nova-scheduler log
  files
