cman init: reorder cmannotifyd startup and allow breakpoints to be configurable
    
    users have requested for cmannotifyd to start earlier in the process
    to be able to dispatch startup notifications.
    
    also some users don't need many of the daemons in the stack at all
    and only use cman for quorum. Allow the breakpoints to be configurable.
