[TRAFODION-2420] RMS enhancementsImproved BMO operation accounting. Two new counters are addeda) scratchIOSize - Size in KB of the scratch IOb) scratchIOMaxTime - Time in microseconds taken by any long pole ESP instance to do scratch IO operationsThe ScrBufSize, ScrBufRead and ScrBufWritten are no longer displayedin the formatted get statistics command outputs.Reduced the default value of CQD HBASE_NUM_CACHE_ROWS_MAX to 1024 from10000 to reduce stress on the client JVM memory.Disabled the memory pressure triggering in the BMO operators by increasingthe threshold GEN_MEM_PRESSURE_THRESHOLD to 10000 from 100. The memorypressure detection code was inadvertently enabled when the cap to limitmemory pressure constant to 100 was removed.Memory pressure triggers in BMO operators will be enabled later whenwe understand the memory pressure detection better.
