Detach and attach boot volumes
At present boot volumes cannot be detached (or attached) after an instance has been created. This blueprint allows boot volumes to be detached or attached when a VM is shutdown. A VM that has had its boot volume detatched will not be bootable.

Detach/Attach root volume API changes
We are two days away from Stein feature freeze and this still needs work and integration testing so I am going to defer it from Stein. We will likely need to talk about some of the design implications that came up late in Stein for this during the Train PTG for things like resetting image metadata when attaching a new root volume with a new image, and handling tags/multiattach volumes. -- mriedem 20190305
