P4TC is missing a push-button packet-test runner

[fruffy]

The BMv2 and eBPF test back ends have push-button test scripts such as run-bmv2-test.py or run-ebpf-test.py. These scripts allow sending a packet with a corresponding control-plane configuration and checking whether the resulting packet is as expected.

These push-button scripts can then be used by tools such as P4Testgen for automated compiler and target test. These scripts are also useful in showing how a particular target can be instrumented and used.

P4TC is missing such a script and workflow, which makes it harder to use or study. It would be great to add such a runner and extend run-tc-test.

@Victor Nogueira @.***> @vbnogueira please look at this. Seems like something simple like arp responder maybe useful to kick it?

Yes, I think arp responder could be an initial example I'll look and sync with Komal on this
