Just as an FYI, there is a bug related to this

https://bugs.launchpad.net/nova/+bug/944383

and similar to

https://bugs.launchpad.net/nova/+bug/953594

We would like to see this functionality as well, but if it is exposed
as an api call, we need to make sure other artifacts are cleaned up as
well.  The fix for the latter bug at least allows us to delete a
volume that is an error state.

In a similar vein, it would be really nice to have a force detach as
described in

https://bugs.launchpad.net/nova/+bug/944383
