Chris Behrens f37fb08c12 Store image properties with instance system_metadata
In implementing adding 'image_meta' to instance notifications,
this was committed:

https://review.openstack.org/#/c/7309
commit 53adfd289bf7226f1c6f59c17608e42f3083f130

However, it's buggy because an instance could have been deleted after we
built from it... and bin/instance-usage-audit uses an admin context with
which we cannot query glance.

This stores image properties with instances in nova as system_metadata
and notifications will use that data.

Fixes bug 997833
