title: How to modify Django admin filter's title
body: <p>I have a filter (one of the defaults and not custom)</p>
  
  <p>Is it possible just to change the title of filter, without write a full new custom filter ?</p>
  
  <p>Because the only customization I need from the filter is its title. THere should be a way to do that without rewriting the whole filter and lookups.</p>
