proto file define the same http annotation with different rpc method

[devkevinyy]

when i use grpc-gateway to proxy the storage gRPC service, i found the same http route in the .gw.pb files.

for example: storage/v1alpha1/frontend_nvme_pcie.proto

rpc ListNvmeSubsystems   (ListNvmeSubsystemsRequest)   returns (ListNvmeSubsystemsResponse)   {
      option (google.api.http) = {
          get: "/v1/{parent=subsystems}"
      };
      option (google.api.method_signature) = "parent";
  }

and

rpc ListNvmeControllers   (ListNvmeControllersRequest)   returns (ListNvmeControllersResponse)   {
      option (google.api.http) = {
          get: "/v1/{parent=subsystems}"
      };
      option (google.api.method_signature) = "parent";
}

above two different rpc method: ListNvmeSubsystems、ListNvmeControllers has the same http anotation url.

Duplicates/relates to #188 ?

[devkevinyy]

not the same, but the issue #188 can also resolve the problem after redefine the rpc methods http anotations according to business rules.
