Generate OpenAPI v3 definitions for the http API

[aaguiarz]

There are some tools like https://www.thunderclient.com/ that don't work with our current swagger definitions.

A new section can be added to this script to convert this openapiv2 file to openapiv3 and place it in /docs/openapiv3/apidocs.swagger.json
