No administrative way to delete an instance in state 'soft-delete'

[Adam Dyess]

As an operator of openstack, if an instance is soft-deleted there's no way to forcefully remove a soft-deleted VM other than wait the appropriate amount of time before the VM is REALLY deleted. Until then it just sits on the hypervisor waiting for its own demise.

I wish there was a command

$ openstack server delete <UUID> --force

or equivalent to REALLY get rid of it from taking up space on a hypervisor.

```
openstack server list --all --deleted | grep SOFT
