[Auto Bench] Integrate push-based CDN to scripts of auto benchmarking on AWS

[dailinsubjam]

Closes #2827 .
Sorry for such a large PR, part of it are changes on simple builder which covers #3210 @QuentinI Let me know if there's a way to separate it into another PR.

This PR:

• Adds script of running benchmarks with push-based CDN
• Adds a README on running benchmarks on AWS and a README on running examples locally with push cdn
• Update and re-organize old scripts with gpu
• Does some changes to benchmark output structure and input parameters
• Covers the simple builder changes of [DRAFT] Builder only on DA nodes #3210 and Benchmarking adjustments #3324
• Adds some benchmark results

This PR does not:

• update the image tag. It's still ghcr.io/espressosystems/hotshot/validator-webserver:main-async-std for now. It seems the new tag will only be created when this runs on main. I will update the tag in the next PR after this one is merged and the image is tested successfully.

Key places to review:

Scripts in scripts/benchmark_scripts.

How to test this PR:

scripts/benchmarks_results/README.md
