Setup CI to run benchmarks and access results

[ghostdogpr]

It would be nice to run benchmarks:

• on demand (manual trigger)
• on each release

Then, the job should gather results and upload them somewhere (gist?) so that we could visualize them like this: https://jmh.morethan.io/?source=https://gist.githubusercontent.com/fwbrasil/27c8abec86e947e9719d41a859deb5d2/raw/814ca4ebb3a1294f8dd7bbec9b54ea0957b92434/jmh-result.json

We can probably copy Kyo's CI: https://github.com/getkyo/kyo/blob/main/.github/workflows/bench.yml

Just to mention that we should probably be a bit selective with which benchmarks to run. e.g., I don't think we need to run the benchmarks for other libraries, and probably just the jsoniter JSON benchmark will do.

Regarding the Nested benchmarks, I think running just the 100 par / batched variants should suffice.

We should probably also reduce warmup and measurement time to 1 second (3 seconds seems like an overkill) to reduce execution time of benchmarks. At the same time, we might want to use @Fork(2) or @Fork(4) as I've noticed that in some cases benchmarks will be significantly slower or faster. I think this has to do with infamous JDK-8180450 issue, and their 12% occurance seems consistent with my observations

Finally, we probably want to check how we're doing comparitively when running multi-threaded vs single-threaded, so we we might want to run

We could start with just running GraphQLBenchmarks and then we fine-tune it from there once the CI is in place.

Here's an example of the end result (I ran the test and uploaded to gist manually): https://jmh.morethan.io/?source=https://gist.githubusercontent.com/ghostdogpr/589d379ba2d096afcbf5a27d4298fb16/raw/e98d61fc0a3d87ad7d31b9f17eeb6596a014a19d/jmh-result.json
