Kirill Gusakov updated IGNITE-19087:
------------------------------------
Description:
Sometimes we must cancel the ongoing rebalance:
* We can receive an unrecoverable error from replication group during the
current rebalance
* We can decide to cancel it manually
For this purpose we need to implement the following parts of algorithm (look at
the [design
doc|https://github.com/apache/ignite-3/blob/c276a334c4c3742520494bccdc957f4530c8ed7a/modules/distribution-zones/tech-notes/rebalance.md]
for details):
* Implement communication between PlacementDriver and PrimaryReplica to start
the cancel process. And the same communication between PrimaryReplica and
ReplicationGroup entity.
* Implement the cancellation itself inside the ReplicationGroup
TODO: separate detailed subtasks must be created
