Description

I think it was decided at some point to deprecate replicaGroupStrategyConfig.

However, right now there's no way to ensure that two tables are partitioned on a given column across the same set of instances, except using a combination of instancePartitionsMap and replicaGroupStrategyConfig.

Given this, let's make sure this is addressed before the config is removed from OSS.

Contributor guide

Research direction
Identify all uses of replicaGroupStrategyConfig in the codebase and design a replacement using instancePartitionsMap to ensure partitioning across instances.
