IMPALA-5354: INSERT hints for Kudu tables
A previous change,
IMPALA-3742, added an exchange node and
sort node to plans for inserts into Kudu tables to partition
and sort the input to match the target table.
This patch enables INSERT hints for Kudu tables - 'noshuffle'
which removes the exchange node from the plan and
'noclustered' which removes the sort node.
Insert hints have no effect for inserts that are small enough
to result in a single node execution.
- Updated FE planner and analysis tests.
- Ran Kudu EE tests.
