This change adds support for the SHELVED_OFFLOADED and (partly)
VERIFY_RESIZE states. Shelved-offloaded instances don't have a
hypervisor associated with them. VERIFY_RESIZE instances should still
be running on their associated hypervisor. They are also present, but
"shut off", on another hypervisor. Even with this change, the code
still generates a warning about the instance being present on multiple
hypervisors. Personally I find the warning quite useful, and I don't
really know what to do about it. Maybe we should suppress the warning
if the instance hasn't been in this state for long.

Adds a very basic one-by-one livemigration tool to remove instances from
a host, but not quite as aggressively as the openstack CLI tool.

Add a JSON output flag to enable this tool to more easily be called by
other scripts and used in pipelines. Re-factor a bit, add a class and
remove some code duplication

This script checks a given Nova Server Group for any instances that fall
foul of invalid anti-affinity rules, i.e there are multiple instances
running on the same hypervisor in a Server Group where the anti-affinity
policy has been set.
Example usage:
./antiaffinitycheck.py --check c353197c-5fbb-410f-a7b3-843452a55276
Anti-affinity rules violated in Server Group: c353197c-5fbb-410f-a7b3-843452a55276

We had a host die last week and it's really annoying to iterate all the
VMs to get customer contact info. That inspired this tool. Given a
hypervisor, get all customer names and emails (pasteable) so that you
can let the customers know about a potential issue. Also useful for
maintenance.
