Assistant feature: Send user query as part of template variable GET request

[ethayu]

Trying to integrate RAG as an assistant. Thinking of using a template variable that makes a GET request (with the prompt as the request body), to get the relevant documents as context. Is this possible (i.e. there is a special variable in the system prompt page for the user query), or is there a better way of doing this?

Found this: #949, but seems to only support time and date. Would be great if something like {{ query }} was supported, and secondly we could query {{url=123.123.123.12:8000/{{ query }}}}, or something like that.

Alternatively, maybe {{url=123.123.123.12:8000/}} could pass the query as part of the request body (as mentioned already)

#611 would also make it doable.
