Ivan Bessonov updated IGNITE-21661:
-----------------------------------
Description:
Following case is possible:
* Nodes A, B and C for a partition
* B and C go offline
* new distribution is A, D and E
* EDIT: rebalance can only be started with one more "resetPartitions"
* full state transfer from A to D is completed
* full state transfer from A to E is not
* A goes offline
* we perform "resetPartitions"
Ideally, we should use D as a new leader somehow, but the bare minimum should
be a partition that is functional, maybe an empty one. We should test the case
This might be a good place to add more tests.
