Public bug reported:

Description: When a host goes down and instances on that host are
deleted while the host is down, this request should be tracked in the
database so that when the host comes back up it can scrub the delete
request against the status of the active instance and delete it if
necessary. The overall goal is for the delete to be processed so that
any attached volumes return to an available state instead of being left
in an in-use state. (attached to a non-existent instance)

This is being experienced while using Cloud Foundry. When the host goes
down, Bosh attempts to re-create the instance along with associating any
previous known volumes.

This has been tested on the following tag:
10.1.18

If this was not an issue, I would expect the delete request to go
through while the host was down and the system itself would clean up the
mess once the host comes back online freeing up the volume for use
immediately.

(This is going to be tested in Liberty as well and further notes will be
attached to the bug report)
