Hello Tidy Bot, Alexey Serbin, Kudu Jenkins, Andrew Wong,

[pruning] KUDU-2671: Pruning compatible with custom hash schemas.

This patch introduces changes to the PartitionPruner class
to be compatible with custom hash bucket schemas per range.

There are three ways to set bounds on a scan.

- Adding predicates (e.g. range/equality)

- Setting lower and upper bound primary keys

- Setting lower and upper bound partition keys

This patch introduces changes that make the first two methods
of setting bounds on a scan compatible with custom hash bucket
schemas per range. The last way using partition keys is unstable
and for internal use only. While it's not necessary for the last
way to be compatible with per range hash bucket schemas, the
entire pruning functionality will not be complete until
PartitionPruner::RemovePartitionKeyRange() is modified.
That work will be done in a follow up patch.
