auto-generated code with gateway/v2 break atlas applications

[seizadi]

Looks like we have switched tooling to gateway/v2, my ‘make protobuf’ broke as infoblox/atlas-gentool:latest emits gateway/v2 stubs. I tried to covert my app to use the new app-toolkit, it compiles but takes a run time error:

proto: extension number 1042 is already registered on message google.protobuf.FileOptions

See https://developers.google.com/protocol-buffers/docs/reference/go/faq#namespace-conflict

I created a new atlas app using:

atlas init-app -gateway -pubsub -health -helm -name cost-insights-backend -registry soheileizadi -kind

I built and ran this app and it gave me the same panic message.

I debugged this problem, Proto ExtensionType being registered that throws error is:

grpc.gateway.protoc_gen_swagger.options.openapiv2_swagger

I removed the following import from my ‘service.pb.go’ auto-generated code:

_ "github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger/options"

The init of the library was registering extension that was causing the problem,
with that change I can run my application now. I am logging this with the gentool but might require additional
supporting atlas app toolkit.
