    [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`.
