IMPALA-5293: Turn insert clustering on by default
This change enables clustering by default. IMPALA-2521 introduces the
'clustered' hint which inserts a local sort by the partitioning columns
to a query plan. The hint is only effective for HDFS and Kudu tables.
Like before, the 'noclustered' hint prevents clustering. If a table has
ordering columns defined, the 'noclustered' hint is ignored and we
issue a warning.
This change removes some tests that were added specifically to test
that clustering can be enabled using the 'clustered' hint. It changes
some tests to use the 'noclustered' hint to make sure that clustering
can be disabled. It also adds tests to make sure that we cover the
'noclustered' case properly.
Cherry-picks: not for 2.x.
