Make tools produce an as-measured test spec

[mfeit-internet2]

There isn't a definitive way to determine whether or not a measurement

For example, the rtt test has a protocol parameter that specifies what protocol should be used to make the measurement. We've always had a "default" behavior of ICMP, which is used by the (preferred) ping tool. There's no way to look at a measurement after the fact and determine what protocol was used other than what tool did it. That's a safe assumption now, but the architecture allows for ways to make that unsafe.

Need to have the system produce a test spec that reflects what was actually measured. E.g., the ping tool would add a protocol of icmp and twping would add a protocol of twamp.

To Do

• Make the can-run method return an additional field containing the as-would-be-run test spec
• Add something to the run containing that data. (It could, in theory, change from run to run.)
