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.
