Generate swagger files from code

The current code is autogenerated from the [swagger file](https://github.com/Call-for-Code-for-Racial-Justice/Open-Sentencing-Aggregator/blob/main/src/main/resources/swagger.yaml). The team would like to switch this around so the swagger/OpenAPI spec is generated from the code. This is easier to manage for the team moving forward.

This [guide](https://openliberty.io/guides/microprofile-openapi.html#augmenting-the-existing-jax-rs-annotations-with-openapi-annotations) examples how to generate openAPI spec from Java code in open liberty.

Next steps
- [ ] create Java models and responses from the existing [swagger file](https://github.com/Call-for-Code-for-Racial-Justice/Open-Sentencing-Aggregator/blob/main/src/main/resources/swagger.yaml).
- [ ] use the guide to add code to generate the swagger file from the Java code created in the step above.
- [ ] compare the old swagger file with the new swagger file to ensure nothing was changed.
- [ ] deploy the new project to the cloud.

@yochanah this might affect the auth work you are doing. Have you already started that work? Do you want to wait till this is finished?
