Add benchmark results processing and deployment

[cz4rs]

fixes kokkos/kokkos#5464

Process benchmark results and deploy generated pages.
Deployment targets deploy-benchmarks branch of this repository and should make the webpage appear at https://kokkos.github.io/kokkos-benchmark-results/.

• repository settings to enable GitHub pages deployment:

• for convenience: enable running workflows on pull requests from forks (for this repository)
• live demo: https://cz4rs.github.io/kokkos-benchmark-results/

Suggested change

	repository: cz4rs/benchmark_monitor
	repository: kokkos/benchmark_monitor

[cz4rs]

Original script: https://github.com/bensanmorris/benchmark_monitor
I have modified / customized it for our use case here: https://github.com/cz4rs/benchmark_monitor

I propose that we fork the original thing and I will deliver my changes with a pull request.

I agree on forking this inside kokkos is the best option

[cz4rs]

Looking back at this, I think this whole step should be removed and benchmark_monitor.py script (plus the templates and requirements.txt) should be added to a subdirectory in this repo.

Did ever get back to this?

Did ever get back to this?

I haven't tested it since the last push (Apr 2023), but functionally this was ready to go at the time. The only change I would make is to simply add benchmark_monitor.py script to this repository instead of checking it out (from a separate repo). The demo at https://cz4rs.github.io/kokkos-benchmark-results/ is still available.

Main drawback is that the results from GitHub runners are no that great (not an isolated environment for reliable performance measurement). IIRC there were talks about having something similar run on Jenkins (with proper isolation and CUDA enabled).
