    Specify availability_zone to unshelve
    
    This adds support, in a new microversion, for specifying an availability
    zone to the unshelve server action when the server is shelved offloaded.
    
    Note that the functional test changes are due to those tests using the
    "latest" microversion where an empty dict is not allowed for unshelve
    with 2.77 so the value is changed from an empty dict to None.
