Add capability to csr to allow N:1 aggregation when ooq is created.

Browse Source 
- This allows applications to force the N:1 aggregation by creating out
of order queue.
- That switches csr to N:1 submission model where commands from multiple
command streams may be aggregated.
- That forces scenarios returning an event to be aggregated as well.
