Commit ac8ffa9125fc3be6f4ceb958ea4930b7834f9292 in impala's branch
refs/heads/master from Riza Suminto

IMPALA-12654: Add query option QUERY_CPU_COUNT_DIVISOR
IMPALA-11604 adds a hidden backend flag named query_cpu_count_divisor to
allow oversubscribing CPU cores more than what is available in the
executor group set. This patch adds a query option with the same name
and function so that CPU core matching can be tuned for individual
queries. The query option takes precedence over the flag.
Testing:
- Add test case in test_executor_groups.py and query-options-test.cc
