Adam Harwell b8ebbe9919 Add cached_zone to the amphora record
This will enable a number of possible features that need to select
amphorae based on their availability zone.

This would allow for quick-lookups on large lists and could be stale,
but it would be expected that future code that uses this would check
with nova for an update if it needs fully accurate data.

Having it be explicitly "cached" should take care of concerns about
users (operators, in this case) being confused about correctness.
Using simply the word "zone" should address concerns about commonality
between compute providers.

The compute zone (if applicable) is now cached in the database and returned
in the Amphora API as `cached_zone`. Please note that this is only set at
the original time of provisioning, and could be stale for various reasons
(for example, if live-migrations have taken place due to maintenances). We
recommend it be used for reference only, unless you are absolutey certain
it is current in your environment. The source of truth is still the system
you use for compute.
