Parallel processor which constitutes of multiple {@link ParallelGatewaySenderEventProcessor}.
Each of the {@link ParallelGatewaySenderEventProcessor} is responsible of dispatching events from
a set of shadowPR or buckets. Once the buckets/shadowPRs are assigned to a processor it should
not change to avoid any event ordering issue.

The {@link ParallelGatewaySenderQueue} should be shared among all the
{@link ParallelGatewaySenderEventProcessor}s.
