BEF Admin Views

Once I get BEF ported to Drupal 8 and all the admin pages in Drupal are ported to Views, we can leverage BEF and Views to build a customized admin UX.

For example, on the admin/people page, it is difficult to find all users without a given permission to perform some sort of bulk operation. Rather than add an "invert this filter" option, which does not always give you the control you need, we can use BEF to build the view using checkboxes with select all/none links and put all that in a collapsible fieldset to keep the exposed form from getting out of hand.

(See #2020167-31: Add a name and email search field to the admin/people view for the original request).

Clearly, this is a D8-only project with no plans to backport to earlier versions.
