Generate Requestctl patterns and rule from a Superset dashboard filters settings

Generate requestctl patterns and rule using the filters selected in the superset dashboards for sampled webrequests.
Simply passing the identifier of the superset dashboard permalink in the URL as

?q=IDENTIFIER

, will load the filter settings saved in that permalink and will generate the related requestctl patterns required to create a rule that filters for the same data.
Some filters will be ignored because they can't be used in requestctl rules and will be listed here below. Review all the content, modify all the occurences of CHANGEME, refine regular expressions as needed. The patterns and rule can be modified in this same page before copying it over to the requestctl repository.
