KUDU-3728 Add range-aware rebalancing to auto_rebalancer
This patch adds support for range-aware rebalancing in the
auto_rebalancer, allowing each range partition of a table to be
balanced independently. This feature was previously only available in
the manual rebalancer CLI tool.
The implementation leverages the existing TwoDimensionalGreedyAlgo
algorithm infrastructure that already supports range-aware balancing
through the TableIdAndTag grouping mechanism. When enabled, tablets
are grouped by {table_id, range_key_begin} pairs instead of just
table_id, allowing the rebalancer to treat each range partition as a
separate entity for balancing purposes.
