When trying to create an instance with the LVM backend, we get an error:

    Fix sizing and quotas nova to lxd on unsupported backends

    The dir and lvm backends don't support sizing and quotas. This was made
    more complicated with LXD3 as "storage" became the default and the dir
    backend, if used, has to be set up as a storage pool. LXD3 is the
    default on bionic. To resolve an openstack-ansible issue and lay the
    ground work for nova-lxd and storage pools and the lxd charm, this patch
    makes resolves sending sizes and quotas for a profile root device on lvm
    and dir backends.
