WIP KUDU-2671: Follow up pruning patch.

This patch modifies how partition key ranges are removed in
PartitionPruner::RemovePartitionKeyRange(). The format of the
field 'range_bounds_to_partition_key_ranges_' is also modified
so the entire set will be reverse sorted as well.

Currently, full scans with no predicates are functional.
Scans with range predicates attached produce the right result,
but the order in which the tablets are returned from the meta
cache are incorrect. They are returned by sorted order of the
hash component first, rather than the range.

The current tests don't include tables with non covering ranges.
They also don't include scans with equality predicates (only
greater or less than predicates).
