Would this really require 3rd party CI if it's just local block storage 
on the compute node (in devstack)? We could do that with an upstream CI 
job right? We already have upstream CI jobs for things like rbd and nfs. 
The 3rd party CI requirements generally are for proprietary storage 

I'm only asking about the CI side of this, the other notes from Sean 
about tweaking the LVM volume backend and feature parity are good 
reasons for removal of the unmaintained driver.

Another option is using the nova + libvirt + lvm image backend for local 
(to the VM) ephemeral disk:
