    Changing deleting stale allocations warning to debug
    
    Deleting the allocations is an expected action, and happens
    frequently so we don't want it to be a warning. It is useful
    as a piece of debug information, however.

  Excessive "Deleting stale allocation for instance" warnings in nova-
  compute logs

Bug description:
  I noticed this here:

  https://review.openstack.org/#/c/460177/12/nova/compute/resource_tracker.py

  Which is part of a refactor, and that warning actually goes back to
  newton:

  https://github.com/openstack/nova/commit/9374566d194be1e861e7d08dd0e3b2a615ff408c

  It shows up a ton:

  http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22Deleting%20stale%20allocation%20for%20instance%5C%22%20AND%20tags%3A%5C%22screen-n-cpu.txt%5C%22&from=7d

  It shouldn't be a warning. This is when we're deleting resource
  provider allocations for instances that are being deleted, it's normal
  operation as far as I can tell.
