3) For non-HA mode, TaskManager uses K8s service to register to JobManager. And
for HA mode, the HA service will be used to retrieve the leader address.
If you want to start multiple JobManagers, then we do not have a documentation
now. I am trying to find some time to work on this FLINK-21382. Please follow
my last comments and change a bit about the args for the session cluster.
