Matt Riedemann 0ce5813698 Add functional regression recreate test for bug 1790204
Since Pike, the FilterScheduler "claims" resources in
placement via allocations based on the flavor during
scheduling. For a same-host resize, the old and new flavor
are summed to get the overall allocation against the single
compute node resource provider, which can cause NoValidHost
failures during scheduling because the sum is over capacity
for the resource provider even though the new flavor alone
may be OK.

This adds a functional regression test to recreate the bug.

Tests for Specific Regressions

When we have a bug reported by end users that we can write a full stack reproduce on, we should. And we should keep a regression test for that bug in our tree. It can be deleted at some future date if needed, but largely should not be changed.

Writing Regression Tests

  • These should be full stack tests which inherit from nova.test.TestCase directly. (This is to prevent coupling with other tests).
  • They should setup a full stack cloud in their setUp via fixtures
  • They should each live in a file which is named test_bug######.py

Writing Tests Before the Bug is Fixed

TODO describe writing and landing tests before the bug is fixed as a reproduce.
