Stop flush should be invoked by cluster members individually when flush coordinator leaves
------------------------------------------------------------------------------------------

                 Key: JGRP-622
                 URL: http://jira.jboss.com/jira/browse/JGRP-622
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6
            Reporter: Vladimir Blagojevic
         Assigned To: Vladimir Blagojevic

Currently when member A who is a coordinator leaves we execute flush coordinator transfer. That is member A starts flush for view V but member B completes it with stop flush. 

Member B, neighbor of A, receives a view V where coordinator is excluded, it takes over completion of flush. However, when B sends stop flush, then stop flush might arrive at member C *before* view V sent by A. Thus events get reordered. 

If each remaining member in V detects (through view) that member A left then each one of the members can complete flush individually by "pretending"  that it received stop flush from A.

This bug is likely to occur only with bundling disabled.
