Balazs Gibizer cc83335987 replace chance with filter scheduler in func tests 
FilterScheduler is the only scheduler driver that properly integrated
with placement api so this patch changes the functional test environment
to use the FilterScheduler instead of the ChanceScheduler.

The amount of vcpu the SmallFakeDriver reports need to be bumped to 2
as during resize to same host the filter scheduler doubles the
allocation on the host. Simply relying on the 16.0 default allocation
ratio does not work as the max_unit of the vcpu does not use the
allocation ratio to avoid that a single server overallocates the cpu.

The only change in unit test is
test_create_instance_with_oversubscribed_cpu which also loads the
SmallFakeDriver and asserts available resources on it.

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.
