Add filtering ability to Chart/Dashboard screenshot API

What is the problem or goal the end user is trying to solve or accomplish?

User is looking for endpoints that will allow to filter chart/dashboard and generate a screenshot out of that

How are they solving it currently?

The chart/dashboard has to be built with the filter applied and saved. This is not feasible when user are looking for ways to dynamically change the filter on the fly and generate the screenshot

What is the recommended solution by the Customer?

Make the endpoint be able to take filter parameter

What are possible workaround?

It’s pretty difficult to document the chart API because the params and query_context schema/structure vary by chart/version. The best course of action is to create the chart through the UI, use the API to fetch the configurations and then start adapting the configurations through the API as needed. So it would require two steps — 1. create a chart using the API and filter params then 2. retrieve the screenshot using the existing chart API
