The default Region implementation will generate EvenTID in the EntryEvent object. This method
is overridden in special Region objects like HARegion or
SingleWriteSingleReadRegionQueue.SingleReadWriteMetaRegion to return false as the event
propagation from those regions do not need EventID objects

@return boolean indicating whether to generate eventID or not
