> In the process of ServerShutdownHandler, we currently assign regions singly.
> In the large cluster, one regionserver always carried many regions, this action is quite slow.
> What about using bulk assign regions like cluster start up.
> In current logic, if we failed assigning many regions to one destination server, we will wait unitl timeout,
> however in the process of ServerShutdownHandler, we should retry it to another server.
