Gmail API v1 Discovery Document

Becomes relevant once gmailr starts to use gargle.

This spec can be used with helper functions to generate requests and process responses once https://github.com/r-lib/gargle/issues/31 is closed.

I am sure this would be useful were you rewriting the package from scratch today, but I am not sure how useful it is with the code already written. But we can revisit later.

If you have no plans to use gargle's request helpers, feel free to just close this.

Well, I guess this one has come full circle now 😆
