[TRAFODION-2420] RMS enhancements
Introduced 2 new counters
HeapWM: - "SQL Heap WM" - Tracks the high water mark of the used memory
including space buffer and bmo operator memory. It is enough to
monitor this counter alone to track the memory utilization of the
query.
scrIOTime: "Scr. IO Time" - Tracks the IO time taken to read/write to
the scratch files at BMO operator level
Introduced a 'Single line Format' option to display BMO stats and SE stats
in a single line format to enable exporting the output to Excel easily.
GET STATISTICS FOR QID CURRENT PROGRESS, OPTIONS 'SL'
Removed and cleaned up the code further
Also fixed memory corruption issues seen with GET STATISTICS command.
