Bug Description

When running XenServer (but possibly on other hypervisors as well), over time, it's possible to enter a state where the database shows an instance as deleted but that instance is still running on the host machine.

This is a placeholder bug to figure out what the root cause is, and to fix it.

As a stop-gap, https://review.openstack.org/#change,2348 is proposed to automatically reap these 'zombied' instances in the dev environments.

    Adds running_deleted_instance_reaper task.

    This adds a periodic task to cleanup erroneously running instances. The
    impetus of the patch was a XenServer specific issue bug #911366, where deleted
    instances would remain running on the host machine.

    The patch however is hypervisor agnostic and is generally useful as a
    housekeeping task to make sure these 'zombied' instances are detected.
