[ ] Validate rebalancing during node outages while maintaining the replication factor.
[ ] Ignore rebalancing when any part of the shards is missing.
[ ] Ensure we are not performing a rebalance during a short-term node outage.
[ ] Check shard rebalancing when a new node is added.
[ ] Validate rebalancing in two cases: 3 nodes with 1 out, and 5 nodes with 2 out (no missing shards, rf=3).

Ignore rebalancing when any part of the shards is missing.

This one is not clear.

Do not rebalance when we lost some shards, for example 5 clusers, 2 node dead, rf=2, we lost data, no need rebalancing
