If an Instance is stuck in BUILD, it cannot be deleted

[Vipul Sabhaya]

Instances that are stuck in BUILD (possibly because GuestAgent failed to start) will never transition to a new state. All operations on this instance are Blocked, including Delete.

I linked this bug to my current blueprint on creating a reset-task-status mgmt call:

[Kevin Conway (kevinconway)]

Is this complete now that there is a reset-task-status call?

[Vipul Sabhaya (vipuls)]

I think the reset-task-status call doesn't quite do what it's supposed to, at least that's been my experience. So it's still still an issue.

I would like to fix this to allow instances in BUILD State to be deleted by the user, instead of having to have Admin Reset state. We need to ensure that during the delete process, we go through and clean up all dependent resources (nova, dns, etc.)

[Dan Nguyen (daniel-a-nguyen)]

I think we've discussed this before. There was a notion of adding a force delete functionality.
Probably involves an api change/mod.

[Denis M. (dmakogon)]

I've got another idea. https://blueprints.launchpad.net/trove/+spec/complete-rollback-if-instance-stucks-at-build-status

Just a heads up - You won't be able to delete an instance if there's not a DNS entry and DNS support is turned on.

The big issue here is I made a PR to address the fact that even if you reset task_id and service_status = 1, you can't remove it.

In order to get this addressed, we have to reorder things in TM. I actually see these delete failures and have to handle them.
