Description

The load balancer logs lines like these:

2019-10-02 23:18:47,664 INFO  [46493_ChoreService_6] balancer.StochasticLoadBalancer - Skipping load balancing because balanced cluster; total cost is 46.68964334022376, sum multiplier is 1087.0 min cost which need balance is 0.05

When balancing per table it would be useful if the table name was also printed in the log line.
