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

[Matt Riedemann]

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.

    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.
