    On Bionic ensure that a default storage backend is configured

    Sets up the default dir backend and configures it as the default pool
    for lxd. This is required on bionic (LXD 3.0.x) as there is no default
    storage pool by default.

    Also installs apparmor which LXD requires to operate, but that is
    missing from ubuntu image that is built for devstack-gate.
