parameter error: Some option you are trying to set is client only

Same problem with variations on --server and --udp

The -u flag isn't needed on the server end with iperf3.  The client negotiates 
with the server to determine UDP or TCP testing.  Probably this should just 
generate a warning rather than an error.

Action item for developers: make this a warning instead of an error and clarify 
man page.

I don't actually agree that this should be a warning, it should be an error 
like all theother bad combinations of parameters. Perhaps with improved wording.

But as it stands, it is a warning now so I'm marking this Fixed.

• Changed state: Fixed

This is still broken though, if attempting to test with multicast (can't get -s 
and -u simultaneously)
