Also we will need to make sure that balancer is always restarted on leader with the new configuration. This would be a separate PR.

sure , will do this

@JacksonYao287 We will also need to add timeout for move with the leader changes. After a leader change the move will be reset so I think we will need to handle the timeouts as well. It might require some thought. Please see if you would like to address it in this PR.
Let's also rename jira and PR to sth like Support move with HA.

thanks @lokeshj1703 for pointing out this. i think it is better off addressing it in a new jira, will do it later
