[rebalance] Add '--known_unhealthy_tservers' flag to rebalancer

Now after removing tservers from a cluster, 'ksck' would report
these tervers as unavailable and rebalancer would not run unless
restarting the masters.
'-known_unhealthy_tservers' is useful for users to run the
rebalancing even if there are some dead tservers in the cluster.
Rebalancer will neglect 'known_unhealthy_tservers' and run on
other healthy tservers.
