[TRAFODION-2420] RMS enhancements
New counters introduced as part of BMO
InterimRowCount - Counter to keep track intermediate rows
produced by hash join and for intermediate
runs in sort
phase - BMO Phase for hash-join and sort
get statistics for statement s1, options 'cs' now works.
Removed attaching BMO stats to Non-root Paritial and leaf partition hash
group by operators.
These operators are non-blocking BMOs.
Introduced 3 phases for hash grby operator to be visible in RMS Stats
options 'sl' now works with get statistics for qid.
The relevant new counters are now part of accumulated statistics type.
Extended the support upto 512 opeartors from 256 operators in RMS
Fixed both Type 2 and mxosrvr code to obtain all the externalized counters
in accumualted stats correctly.
