Configure result columns, page size and sort infos in filter form

Currently it is not easy or not possible to configure result columns, page size and sort infos from the filter form of a content view in Studio.

Here is a rough list of what is needed:

• provide widgets that can be easily added to the filter form for each of these items
• appropriately configure the page size binding, sort infos binding and result columns binding on the content view (only available in advanced configuration for now)
• add the content_view_display schema (or ideally facet to the search document model type).
• make sure all this is set or discarded for advanced search form (and content views flagged as advanced search)

The page size widget type would also need to be made configurable (to chose what values are available) and made consistent with the default selector on the content view display.
