> We must improve logging of rebalance logic with the following points:
>  - log triggers of rebalance (change of number of replicas at the moment)
>  - log receiving of changes on pending/stable keys
>  - log start/stop raft nodes with the info about the reason
>  - log the result of multi-invoke call (we can use `yield` to detect which branch was executed)
>  - log the call of changePeersAsync on the client side
>  - log the real error of the call above, if error occurred (we need to change the error reporting of sendWithRetry method to support this point)
>  - check if needed extensions of raft logs for changes in raft group configuration
>  - log the progress of raft replication during rebalance (it can be tricky enough, due to the fact, that replicator has no information about the reason of replication)
>  - logging for onLeaderElected/onNewPeersConfigurationApplied/onReconfigurationError
> All logs should contains the most detailed context:
>  * table
>  * partition
>  * metastorage keys' values (old/new)
