BooleanArrFilter for Admin and Dashboard pages;

Please add logic described on #574 (closed) for filters:

1. "Descriptor is in use" filter on the /dashboard/descriptors page;
2. All filters in the "Status" block, on the /admin/users page;
3. Template filter on the /admin/content page;

Also have a look that we should implement BooleanArrFilter logic for:

1. Filters in the "Tidbits" block in the dataset publisher and Descriptor list publisher;
