    Failback will enable the host that has been frozen

    If user freezes the host before failover, the cinder volume serivce
    will be enabled by failback, and user doesn't need to thaw the host
    before modify the host, if this is expected, the 'Frozen' field in
    cinder service list should be changed to 'False', but it may be better
    that host that is frozen must be thawed.
