Description

Controlled shutdown in KRaft is signaled through a heartbeat request with the `shouldShutDown` flag set to true. When we begin controlled shutdown, we should immediately schedule the next heartbeat instead of waiting for the next periodic heartbeat so that we can shutdown more quickly. Otherwise controlled shutdown can be delayed by several seconds.
