IMPALA-6151: add query-level fragment/backend counters
This adds NumBackends, NumFragments and NumFragmentInstances
counters to the query profile to make it easier to manually or
programmatically analyse the query.
Testing:
Ran "select count(*) from alltypessmall" and checked profile:
Backend startup latencies: Count: 3, min / max: 1ms / 1ms, 25th %-ile: 1ms,
50th %-ile: 1ms, 75th %-ile: 1ms, 90th %-ile: 1ms, 95th %-ile: 1ms, 99.9th
%-ile: 1ms
