Add benchmark for performance regression testing

[justin-tay]

This adds benchmarks for regression testing by adding benchmarks using jmh. This is in preparation for starting to add the breaking changes to prepare for 2.0.0 since Jackson 3.0 is likely to be released soon, so that those changes don't result in performance regressions.

This automates the running of the benchmark by adding a benchmark.yml workflow that runs the benchmark for all push to master that uses github-action-benchmark to publish updates to a GitHub Pages to the gh-pages branch under /dev/bench.

This also updates the tests to remove the use of the undertow server. Instead a SchemaLoader is used to load the files directly.

@stevehu is it possible for you to enable GitHub Pages in Settings > Pages? That way the pages-build-deployment action will run to deploy the gh-pages branch and the benchmark chart will then be easily seen from https://networknt.github.io/json-schema-validator/dev/bench. Thanks!

[stevehu]

@justin-tay I have made the change, but I am not certain if it is complete or not. I can see the page shows up when you click the link. Is this all we need? Thanks.

[justin-tay]

@stevehu Yes that's all that's needed. Thanks!
