#3139 [Housekeeping] Migrate protobuf stub generation to buf Issue created by eapolinario Describe the issue We currently rely on a series of old (and very-hard-to-update) code to generate the stubs for the different languages we support in flyteidl. Instead we should leverage buf and move over the step at which we generate the stubs, e.g. if we adopt buf remote plugins we don't even have to maintain generated stubs. What if we do not do this? It's nearly impossible to update the original script, this makes it hard for us to adopt newer technologies, for example grpc-gateway v2 (which includes the swagger/openapiv2 annotations).
