PREVIEW 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
distributed 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.
