Lars Volker c24e9da914 IMPALA-2521: Add clustered hint to insert statements
This change introduces a clustered/noclustered hint for insert
statements. Specifying this hint adds an additional sort node to the
plan, just before the table sink. This has the effect that data will be
clustered by its partition prior to writing partitions, which therefore
can be written sequentially.
