    cluster/ec: Handle CHILD UP/DOWN in all cases

    Problem:
    When all the bricks are down at the time of mounting the volume, then mount
    command hangs.

    Fix:
    1. Ignore all CHILD_CONNECTING events comming from subvolumes.
    2. On timer expiration (without enough up or down childs) send
       CHILD_DOWN.
    3. Once enough up or down subvolumes are detected, send the appropriate
event.
       When rest of the subvols go up/down without changing the overall
       ec-up/ec-down send CHILD_MODIFIED to parent subvols.
