    Fix nova-lxd tests for bionic.

    This patch adjusts the nova-lxd deployment so that it works correctly
    with LXD3 and bionic.

    * Update the zuul job and project config to switch from xenial to bionic.

    * Change the variable lxd_storage_pool to always have a defined value
      in the role defaults. This variable represents the name of the LXD
      storage pool which is distinct from any names associated with underlying
      storage. LXD storage pools created with 'lxd init' are always called 'default'.

    * Switch the role test storage backend from dir to ZFS. nova-lxd is
      currently not working for the dir backend as it expects the storage
      subsystem to support quotas.

    * Due to limitiations in nova-lxd it is necessary to ensure that the
      LXD storage pool name and ZFS pool names are both set to 'default'.
