In case during rebalance some members joined or departed rebalance will automatically restarted.
But from the user side it can not see on how many members rebalance was executed.
We have a situation when have 3 servers and during rebalance one is departed and rebalance is executed on other 2 servers. But after rebalance is finished server is back and user have a wrong perception on how many servers rebalance is executed.
It will be good to have another row in result table to print this message.
