    Add node recovery callbacks · cf921cc1
    Goldwyn Rodrigues authored
    DLM offers callbacks when a node fails and the lock remastery
    is performed:
    
    1. recover_prep: called when DLM discovers a node is down
    2. recover_slot: called when DLM identifies the node and recovery
    		can start
    3. recover_done: called when all nodes have completed recover_slot
    
    recover_slot() and recover_done() are also called when the node joins
    initially in order to inform the node with its slot number. These slot
    numbers start from one, so we deduct one to make it start with zero
    which the cluster-md code uses.
