Look into the test data the client is sending to the server

[ndfred]

Looking at send_results we can see that the client will dump a lot of useful information to the server:

{
"cpu_util_total": 18.970173953262933,
"cpu_util_user": 3.7781612782127576,
"cpu_util_system": 15.191864176430617,
"sender_has_retransmits": -1,
"streams": [{

}

Maybe we can pick some of these up to provide better data in the UI. For reference, this is what the same completed test looked like in the app:
