Added an initial openapi protobuf generator for our resource APIs.

[mkeeler]

Description

I wrote a protobuf generator to output openapi specs for all our resource API groups.

Areas for improvement:

• Handling of doc comments need some improvement.
  • stripping // from the beginning of lines
  • better HTTP path/operation docs
  • high level resource docs attached to the component schemas
  • external docs links eventually
• Annotations for field validations
• Support for knowing whether a resource can be imported/peered.

Testing & Reproduction steps

• Ran openapi linters to ensure things are okay.
• Opened openapi previews using a vscode extension to ensure the auto-generated docs look right.
