additional_bindings not generate multiple paths

[juchaosong]

We use additional_bindings to defice multiple URI bindings referring to HTTP and gRPC Transcoding. But it seems not generate multiple paths in openapi documentations.

I fork the repo, add commit https://github.com/juchaosong/gnostic/commit/5752cb1b52c4cfcb50bc4d6bc012ac7b681e6f75 using additional_bindings. Use the following cmd to generate openapi.yaml:

cd cmd/protoc-gen-openapi
protoc -I examples/ --openapi_out=. examples/google/example/library/v1/library.proto

But only POST /v1/shelves/{shelf}/books generated. Thanks for your respondings.
