Fix bug in request details filter, and update preprocess response

[ingeniumed]

Description

This PR is meant to update the request_details filter, to not overwrite the query with a string representation of the query params. Also, this implements a possible solution for the problem identified in #594 - remove the input_variables and replace it with request_details instead. The request_details is used to store the row_id in the headers if by the Google Sheets data source and then the filter is used to inject this in the pre-process response. This allows for the cache to work as expected, and for the query to return the correct response as well.

Testing

• Setup a Google Sheets data source
• Insert a block for this data source
• Ensure this works as expected by picking a few entries, and ensuring they show up correctly
• Updating the row ID in the query Inputs panel should reflect this as well.
