List of dimensions available in a view

[enzomaruffa]

Hi folks!

I have a specific scenario where getting a list of all dimensions available in a view into a Liquid variable would be extremely helpful. As of now, we have been using an `allDimensions` list manually written 😅. For context, this would be inside an `sql:` field the very same view. 

Is there any sort of way of doing something such as this? Or, event better - a list of all dimensions that are _in_query?

My worst case scenario solution is to find an endpoint that I can hit to at least programmatically generate this list and update it every once in a while. 

Appreciate any help!
