Is it feasible to add a rights param to the pageimages api to allow querying by non-free+free or free?

The idea is that hovercards has aproval for getting non-free images but other extensions like related articles don't, so we need to have a way on the same wiki to query pageimages specifying all images or just free.

the only issue I can see is that for some pages we will need to calculate and store 2 page image properties for roughly 18% of pages [1] (free and nonfree). We can then add an api parameter to express a preference.

Given a page property is a title this doesn't seem like a big storage issue to me.

Also please merge or reword to be Hovercards specific. This request has been captured in T131105 for some time so let's not fragment the conversation.

@Jdlrobson - I think it's possible for the two to be merged. Or rather, what we want is to:

1. do T131105: Pageimages should return both free and non-free images with 'free-ness' denoted as a property (merge or track there)
2. set non-free for all features, set free for hovercards (merge or track separately in this card)

@ovasileva - to update specifically for hovercards

I met with @mobrovac and @Pchelolo today and informed 'em that Reading Web would be updating the PageImages API to return free images by default (see T152216: Return free images by default) and, consequently, they'd have to update the page summary definition to include pilicense=any in the internal PageImages API call.

And I've created a PR to add it: https://github.com/wikimedia/restbase/pull/741

This has been merged and deployed, so you can go ahead and start using RB's summary endpoint.
