Ability to add a "label" to the output lines

[GoogleCodeExporter]

When testing the total performance from a single multi-homed host, I often do 
something like this:

iperf3 -p 5210 -i1 -t 60 -P2 -R -w128M -c 10.60.4.1 &;  iperf3 -p 5410 -i1 -t 
60 -P2 -R -w128M -c 10.60.5.1 &

But then I cant tell which output line is from which command.

I'd like a -label option, so that I can do:

iperf3 --label "test 1: "-p 5210 -i1 -t 60 -P2 -R -w128M -c 10.60.4.1 &;  
iperf3 --label "test 2: " -p 5410 -i1 -t 60 -P2 -R -w128M -c 10.60.5.1 &

and then all the output to stdout would have the label at the beginning of the 
line.

This label should show up as a field in the JSON output as well.

Here is an example from nuttcp that demonstrates this:

nuttcp -T20 -i1 -w400M -xc 2/2 -Is1 -p 5500 10.26.0.132 & nuttcp -T20 -i1 
-w400M -xc 3/3 -Is2 -p 5501 10.26.0.132

We're using -L for the TCP flow label, so we'll have to come up with a 
different flag for this.  We could copy nuttcp and use -I, but how about -T / 
--title?  We're not using "title" anywhere in the code right now.

Also, I think I'll add the ": " punctuation automatically, so you only have to 
specify a simple string. Looks like nuttcp does this too.
