In a cluster, if you execute "asadmin disable --target <cluster-name> <appname>", it does not send the
event parallelly to the instances. That is a problem.
At the same time, if the target is domain ("asadmin disable --target domain <appname>" , it does send
the event parallelly to the server. The issue is only when cluster name is used as the target.
I did some debugging.... Look like the following class when it uses ElementChangeHelper ends up
sending the events sequentially.
