> In case of a heartbeat timeout, the {{TaskExecutor}} closes the connection to the remote
component. Furthermore, it assumes that the component has actually failed and, thus, it will
only start trying to connect to the component if it is notified about a new leader address
and leader session id. This is brittle, because the heartbeat could also time out without
the component having crashed. Thus, we should add an automatic retry to the latest known leader
address information in case of a timeout.
