add benchmark to phoronix-test-suite/openbenchmarking

I'd love to bench c-lightning benchmark more often with larger scale of hardware (mostly CPUs) as that's my main job but last time I tried it, I ran into many issues and spent hours to get it running.

It would be best to add the benchmark to https://github.com/phoronix-test-suite/phoronix-test-suite and https://openbenchmarking.org/ so people can ran it with single command. That way we could get large dataset of hardware and of improvements being made across different versions.

Thanks

Longtime Phoronix follower myself, sounds like an awesome idea. Question however is what aspect of the nodes do we want to benchmark? Options are throughput, latencies, number of channels, etc and some of them are hard to test in isolation, or aren't that decisive (throughput may be good, but synchronicity in the protocol may force us to be bottlenecked on latency).

Once we have decided on the benchmark dimensions we could instrument the nodes to make an integration possible 👍
