[HTTP/OAS] Commit OAS snapshot (#183338)

Close #181992

## Summary

First iteration of a CLI to capture an OAS snapshot.

## How to test

Run `node ./scripts/capture_oas_snapshot.js --update --include-path
/api/status` and see result in `oas_docs/bundle.json`.

If you have the [bump CLI](https://www.npmjs.com/package/bump-cli)
installed you can preview the hosted output with `bump preview
./oas_docs/bundle.json`

## Notes
* Added ability to filter by `version`, `access` (public/internal) and
excluding paths explicitly to the OAS generation lib
* Follows the same general pattern as our other "capture" CLIs like
`packages/kbn-check-mappings-update-cli`
* Result includes only `/api/status` for now, waiting for other paths to
add missing parts
