> Scenarios for testing: (current storages: *TxStateStorage* and *MvPartitionStorage*)
> * During a full rebalance, the leader changes, what will happen?
> I expect the current rebalance to be canceled and a new one to start with empty storages and set initial (equal to 0) *lastAppliedIndex *and *lastAppliedTerm*.
> And also what index will be sent to the new leader, if during a full rebalancing on the recipient it will be equal to *-1*.
> * What happens if a leader changes during a full rebalance that has enough log to avoid a full rebalance?
> I expect the full rebalance to be canceled, clear the storages and set the initial (equal to 0) *lastAppliedIndex *and *lastAppliedTerm*.
> And also what index will be sent to the new leader, if during a full rebalancing on the recipient it will be equal to *-1*.
> * Suppose a full rebalancing for one of the storages ended successfully, and it has updated (not equal to -1) *lastAppliedIndex *and *lastAppliedTerm*, while for the other we did not have time to complete the full rebalancing and the node fell.
> What will happen to both storages after the node is powered on?
> I expect both stores to be cleared and have initial (equal to 0) *lastAppliedIndex *and *lastAppliedTerm*.
> Each scenario can be tested in a separate ticket
