KUDU-2914: Rebalance tool support moving replicas from some specific tablet
servers
Aims to support moving replicas from specific tablet servers,
this patch re-uses the '--ignored_tservers' flag and adds a
'--move_replicas_from_ignored_tservers' flag to the
`kudu rebalance cluster` CLI tool.
Once the flag '--ignored_tservers' is specified, and the flag
'--move_replicas_from_ignored_tservers' is specified false,
the given tablet servers are not considered as a part of the
cluster, their health state and replicas on them are ignored
by the rebalancer tool.
If '--move_replicas_from_ignored_tservers' is specified true,
unhealthy tservers in the given tservers will also be ignored by
the rebalancer tool. But for healthy ignored tservers, replicas
on them would be moved to other tservers before starting the
rebalancing process, when running the rebalancing, these tservers
are not considered as a part of the cluster.
