Performs the flush of the cluster but only for the specified flush participants.
<p/>
All pending messages are flushed out but only for the flush participants. The remaining
members in the cluster are not included in the flush. The list of flush participants should be
a proper subset of the current view.
<p/>
If this flush is not automatically resumed it is an obligation of the application to invoke
the matching {@link #stopFlush(List)} method with the same list of members used in
{@link #startFlush(List, boolean)}.

@param automatic_resume
if true call {@link #stopFlush()} after the flush
