[RfC] Fix URL too long (#6519) 

When a URL gets too long (usually happens with controls that allow
free form text), it creates an array of bugs.
* bug when creating a short URL, because the POST request's referrer
field is too long
* a bug when saving a chart (when the modal shows up) also because of
the referrer being too long

Some work has been done in the past to mitigate this, and I'm unclear if
it's some sort of regression because of the Flask upgrade or some
browser change, or whether these bugs have always been around.

This is a request for comment on an approach that works. Let me know if
you can think of better ideas as to how to manage this.

My current solution looks for 8000+ characters URLs and shrinks them to
only `/superset/explore/?URL_IS_TOO_LONG_TO_SHARE&form_data=...` and we
only keep the formData keys for `datasource` and `viz_type`. Not super
elegant but does the trick.
