This PR fixes #903 and implement what is described in proposal 71.
It adds the new /openapi/v3 endpoint to return the OpenAPI v3 specification.
It also adds the new /openapi/v2 endpoint returning the OpenAPI v2 specification as the already existing /openapi endpoint.
That's for deprecating the OpenAPI v2 specification, incouraging users to use the v3 endpoint because v2 will be removed at the beginning of 2025 (as per proposal above).
