Log additional query params

Problem/Motivation

Some popular referral sources add their own tracking params
FB / IG adds: fbclid=XXXXXX
Mailchimp adds: mc_cid=XXXXXX&mc_eid=XXXXXX
Google has: utm_* params

There are others but these are just off the top of my head.

It may be useful to log these on the click entity, so we can have some more details for reporting.

Maybe it can be handled in a submodule when the click entity is created, so the implementing site can decide what is valuable to them.
