Matt Riedemann 5ec5886fe7 Add regression test for rebuilding a volume-backed server 
Commit 984dd8ad6a makes rebuild
check to see if the user is rebuilding an instance with a new
image and if so, to run the scheduler filters again since the
new image might not work with the current host for the instance,
and we rebuild to the same host that the instance is already
running on.

The problem is the instance.image_ref attribute is not set for
a volume-backed (boot-from-volume) instance, so the conditional
in the rebuild() method is always True, which means we always run
through the scheduler for volume-backed instances during rebuild,
even if the image in the root disk isn't changing.

This adds a functional regression test to recreate the bug.

Conflicts:
      nova/tests/fixtures.py

NOTE(mriedem): The fixture conflict is due to not having the
CinderFixture in Newton. That was added in Ocata via commit
47fb8b7579. It's added here in
it's entirety since that is simpler than trying to basically
re-write it from scratch in a backport.

NOTE(mriedem): The functional test is slightly modified to
not rely on Placement and because of old config option names.
