   This was discussed in the Pulsar community meeting. Some notes from the discussion:
   - PR #12818 changes should be reverted so that API could be kept backwards compatible.
   - It’s possible to have the current v2 API for creating persistent topics to handle multiple different payload types
   The challenge seems to be that in the old method, the number of partitions was passed in the payload as a single integer without having a JSON object at all. This makes it harder to extend the existing API, but doesn’t make it impossible.
   - One possible solution is based on request’s “Content Type”
   `Content-Type: application/vnd.some-custom-identifier+json` on request, `@Consumes("application/vnd.some-custom-identifier+json")` on method that handles the new payload type. It also needs an annotation that the newer payload uses the custom mime type.
