Mark /metric-payload-options optional in docs

[zeisss]

When the payload type is select or multi-select and the payload options configuration is empty, expanding the drop-down menu will trigger this API. The request body will carry the current metric and payload.

I recently implemented the endpoints, but missed the /metric-payload-options endpoint (thus serving a 404). The docs state this endpoint is requested to fill the payload options, if they are empty, but I am still seeing requests to this endpoint even though I always serve the options when describing the available metrics.

It feels like the docs are a bit inconsistent from what I am seeing: a) It doesn't seem to actually be required since it works just fine as I am serving a 404 and provide the options in the initial metrics structure b) The docs state this is only requests if the options are empty, but I am still seeing requests

👋🏾 can you send PR with a fix? I believe it is in QueryBuilderPayloadSelect

So we want to follow a) the docs and skip the request or b) just update the docs to mention the request will be made anyways, but a 404 is fine?

I think the datasource should not make the request as stated in the docs now (?)
