move to oapi codegen
This is a major refactor moving from go-swagger to oapi-codegen.
This is due to go-swagger not supporting (and not going to support) openapi 3 (see https://github.com/go-swagger/go-swagger/issues/1122)
This also changed a couple things:
- Swagger 2.0 -> Openapi 3.0
- Making more settings configurable through envvars (ex. build_id_prefix)
- Added an option to run the server out of a k8s cluster (will use your local kubeconfig) -> out_of_k8s_run
It's a backwards compatible refactor, so no external functional changes should have happened.
Bug: #338478
