How to declare context for LSP?

[schiegl]

What are ways to tell the LSP about the context of the current template? For example, when rendering a template I'm passing a list that is iterated in the jinja for loop. At the moment all the variables I'm referencing are "undefined", since the LSP doesn't know which context I will render the template with.

I haven't implemented goto reference, maybe that could help with context.
