[FLINK-2499] [scripts] Warning message for hosts starting multiple da…
…emons
As per the discussion on the relevant
[ticket](https://issues.apache.org/jira/browse/FLINK-2499) adds a warning
message.
I decided against the latest comment of @StephanEwen on the issue, because
I have also run into (accidentally) trying to stack multiple JobManagers on the
same machine and it is nice to have this warning even in that case.
This solution is a bit too verbose in test setups with a lot of
TaskManagers on the same machine, but keeps the PID related code in the
`flink-daemon.sh`.
