When running a cluster where nodes have multiple stores, one store often seems to get a disproportionate number of replicas allocated to it.

Here's an example cluster with 5 nodes, each with 5 stores:

This is happening on 3 of 5 nodes in this cluster. We currently do not rebalance between multiple stores in the same node, but we may want to consider it for performance reasons. For example, maybe each store is backed by a different SSD. Spreading our I/O evenly across stores could benefit performance.
