Mark queries in Data config if used in screen/DP

[vaskoZGU]

In applications with many queries, it would be helpful if those used in screens/DPs had a label like "in use".
Similar to Portainer, which shows the images in use.

Hey @vaskoZGU,

I do like this idea.

I think this may be better as feature request on Github issues instead of a discussion.

There's a similar issue raised here: #9686

It would be nice!

@melohagan Thanks, that's exactly what I was thinking too.
