Filter PageChooserPanel queryset

It would be great if you could filter Pages on PageChooserPanel using a queryset.

Something like:

PageChooserPanel('link_page', queryset=EventPage.objects.live().descendant_of(events_index)),

Not quite the same as specifying the QuerySet per PageChooserPanel, but this issue is one of the top results for filtering the PageChooserPanel through any means so I thought it would be good to link to this relevant wagtail hook: https://docs.wagtail.io/en/v1.11.1/reference/hooks.html#construct-page-chooser-queryset

That hook might then be used like:

@hooks.register('construct_page_chooser_queryset')
def limit_page_chooser_to_site_specific_pages(pages, request):
    try:
        return pages.in_site(request.site)
    except Exception as e:
        # couldn't filter by site so return untouched pages queryset
        return pages

In order to achieve the site-limited query sets mentioned by @cnk.

@brylie Overriding get_object_list is indeed the way to go.
