Fix permissions to /var/lib/nova/

Due to changes with the drop-root work, we lost the ability to write
to /var/lib/nova/*. This fixes those permissions and ensures cross
container talk works properly between nova_libvirt and nova_compute

Additionally, this fixes another issue introduced which saw that
nova-compute could not run sudo commands as it did not have a proper
sudoers entry

Testing from previous deploys means you need a fresh environment. You
have to remove all of the named volumes that kolla created in docker.
Check these with `docker volume ls`
