Improve EC shards rebalancing logic across racks (#6270)

Browse Source 
Improve EC shards rebalancing logic across racks.

  - Favor target shards with less preexisting shards, to ensure a fair distribution.
  - Randomize selection when multiple possible target shards are available.
  - Add logic to account for replication settings when selecting target shards (currently disabled).
