Hmm, to me it is confusing by itself that there are different parameters
for ports in HA mode and in standalone mode.
Taking a step back, I would expect this behavior: `jobmanager.rpc.port`
should be interpreted by HA and non-HA the same way:
- If it is a single port, that port should be used.
- A `0` should pick a random port.
- A portrange should pick a port from the range.
Portranges and random ports are only cornercase useful in standalone
setups, but might be. One can start a flink cluster with a port range port, and
submit a job via the web frontend, or by explicitly specifying hostname:port in
the CLI client.
