> The controlled shutdown mechanism should be integrated into the software for
> better operational benefits. Also few optimizations can be done to reduce
> unnecessary rpc and zk calls. This patch has been tested on a prod like
> environment by doing rolling bounces continuously for a day. The average time
> of doing a rolling bounce with controlled shutdown for a cluster with 7 nodes
> without this patch is 340 seconds. With this patch it reduces to 220 seconds.
> Also it ensures correctness in scenarios where the controller shrinks the isr
> and the new leader could place the broker to be shutdown back into the isr.
