Fixed protobuf

[oxisto]

• Added back missing protobuf generation
• Fixing problem with duplicate operation IDs
• Moving openapi.yaml into distinctly named files in preparation for confirmate restructuring

The last two items require a custom tool that changes the operation IDs because of a bug in gnostic (see https://github.com/google/gnostic/issues/372)
