The Swagger specification indicates that all operationId values should be
unique. However, SwaggerParser doesn't complain during validation if that
doesn't happen, so this commit adds our own method to identify these
cases.
Also, the violations of this rule have been fixed.
Introduce Swagger UI and the Swagger/OpenAPI specification. Explain
the structure of zulip.yaml and show examples of different sections

This is a new file in /docs not yet included in the Read the Docs
table of contents. Where it should go should be determined as we iterate
on the Swagger UI integration and expand REST API doc coverage using it.
For more on Swagger UI and how Zulip uses it, see:
