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.
