Alex Behm 7efa08316e IMPALA-4572: Run COMPUTE STATS on Parquet tables with MT_DOP=4. ...

COMPUTE STATS on Parquet tables is run with MT_DOP=4 by default.
COMPUTE STATS on non-Parquet tables will run without MT_DOP.

Users can always override the behavior by setting MT_DOP manually.
Setting MT_DOP to 0 means a statement will be run in the
conventional execution mode (without intra-node paralellism based
on multiple fragment instances). Users can set a higher MT_DOP
even for Parquet tables.

Testing: Added a new test that checks the effective MT_DOP.
Locally ran test_mt_dop.py, test_scanners.py, test_nested_types.py,
test_compute_stats.py, and test_cancellation.py.
