Bug description:
  [Impact]

  CI run: https://ci.lscape.net/job/landscape-system-tests/2451/

  gs3 log attached. Below some excerpts:

  It looks like the problem started when it uploaded the first image (14.04) to glance. That failed:

  [Test Case]

  Found evidence in the juju logs for glance/0 that it restarted right at 13:37:07:
  2016-05-18 13:37:07 INFO ceph-relation-changed ^MReading state information... 0%^MReading state information... 0%^MReading state information... Done
  2016-05-18 13:37:07 INFO juju-log ceph:50: Loaded template from templates/ceph.conf

  2016-05-18 13:37:07 INFO ceph-relation-changed glance-api start/running, process 62839

  glance/1 had its last restart later:
  2016-05-18 13:32:01 INFO ceph-relation-changed glance-api start/running, process 31045

  glance/2 at that time too:
  2016-05-18 13:32:00 INFO ceph-relation-changed glance-api start/running, process 30584

  In gs3, a few log entries later, we can see that 14.04 is in state "saving" in glance:
  (...)
  {"images": [{"status": "saving", "deleted_at": null, "name": "auto-sync/ubuntu-trusty-14.04-amd64-server-20160516-disk1.img", "deleted": false, "container_format": "bare
  (...)

  It remains in this state throughout the logs.

  gs3 then proceeds to download 16.04, upload it to glance, and then
  finally publishes the streams. It's unknown if 14.04 is part of this
  publication or not.

  [Regression Potential]

  This part was added specifically for the Xenial backport, including:

  - 433-glance-ignore-inactive-images.patch (LP: #1583276)

  And chances of regression are small based on the MR feedback from SEG
  and this particular bug already stating the issue was fixed.

  [Other Info]

  Landscape however fails, because it doesn't find enough "active" images:
  May 18 14:33:29 job-handler-1 INFO  RetryingCall for '_wait_for_active_image' failed, will try again.
  May 18 14:33:29 job-handler-1 INFO  Traceback: <class 'canonical.landscape.model.openstack.jobs.errors.NoActiveImageAvailable'>: #012/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:393:callback#012/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:501:_startRunCallbacks#012/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:588:_runCallbacks#012/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:1184:gotResult#012--- <exception caught here> ---#012/usr/lib/python2.7/dist-packages/twisted/internet/defer.py:1128:_inlineCallbacks#012/opt/canonical/landscape/canonical/landscape/model/openstack/jobs/images.py:48:_wait_for_active_image
