PR #1284 completely removes the `/api/v1/update/replace` endpoint. This endpoint is not being used by any other services in Metron currently.
As part of the work I am doing to allow Elasticsearch to auto-generate the document ID, I would have had to make code changes to this endpoint to continue to support it. Rather than doing that, I opted to remote it, as I believe it is dead code. * I want to make sure that no one in the community is using this endpoint for other purposes. If you are, please respond on this thread. * Does anyone think we should deprecate this before completely removing it? Personally, I do not think it is necessary, but if anyone disagrees please voice your opinion.  https://github.com/apache/metron/pull/1284
