Add more winsync support to cli
    
    The ipa-replica-manage list, init, and synch commands do not work for winsync
    agreements.  This patch adds that support and some additional verbose logging.
    
    The synch_master did not work correctly.  The way it should work is to set
    the replication schedule to some bogus value, then reset it back to its
    original setting.  This will force replication to take place immediately.
