Display treatment for newly added entities

As a user, I want to have a visual confirmation the entity I created is viewable in the overview page.

Acceptance Criteria

• Newly created entities are grouped under a "Just added" section
• New entities are displayed on top, regardless the sorting selection until:
  • User navigates away from page (opening Cask market/resource center modal shouldn't be considered navigating away from page)
  • User manually refreshes the page
  • User changes filters, sorting or performs a search
  • User quits or logs out of CDAP
• Previous sorting selection persists for old entities which are displayed below the new entity(ies) set.
• New entity is highlighted by a green outline for 3 seconds
