* Added OpenAPI document link to usage
The OpenAPI document at /api/swagger.v1.json needs an obvious reference. Sadly, I am English monolingual, so someone else is going to have to do the other languages. In the mean time, this PR should help anyone looking for the file.
* Update docs/content/doc/developers/api-usage.en-us.md
