Change subject: IMPALA-8097: mt_dop for all queries via hidden flag ...................................................................... IMPALA-8097: mt_dop for all queries via hidden flag --enable_all_mt_dop=true unlocks mt_dop for all queries including joins and inserts. This disables the parallel plans with separate join builds when running standalone, because these are not executable. Inserts work without modification - they were disabled because of lack of testing and the possibility for generating many small files with unpartitioned inserts. Testing: Add custom cluster test that exercise joins, runtime filters and inserts as a sanity check for the flag. Ran exhaustive build. Manually ran TPC-H and TPC-DS tests against a minicluster with mt_dop = 4.
