Ivan Bessonov updated IGNITE-21284:
-----------------------------------
Description:
We need an API (with implementation) that's analogous to
"reset-lost-partitions", but with the ability to reuse living minority of nodes.
This API should gather the states of partitions, identify healthy peers, and
use them as a new raft group configuration (through the update of assignments).
We have to make sure that node with latest log index will become a leader, so
we will have to propagate desired minimum for log index in assignments and use
it during the voting.
