Code Issues Proposed changes

Allow devstack plugin to manage zfs 

Allow devstack to install the zfs package
for Ubuntu and create the needed zfs pools.

This will only happen when LXD_BACKEND_DRIVER
is set to zfs otherwise no configuration will
take place.

The goal is to use this with nova-lxd devstack-gate.
