As a user, I can quickly manage/modify my search facets

Particularly when you have large sets of metadata, it can be difficult to see/manage the aggregates chosen to facet on.  Likewise, when you want to remove facets, you have to scroll throughout all your aggregates to remove values from your query.

AC:

• I see a listing of the values I've selected as aggregates for my query
• I see a way to remove the selection from my query
• When I remove an item from my query, the search results are updated
• when I have a long list of aggregates/filters, i have a vertical scroll bar and the "clear filter" action is fixed at the bottom
• When I have 0 filters we show an "empty state"
• The feature works in RTL mode
