Drawers: An easy way to show define a drawer

Instead of a drilldown action going to a drildown view, some actions could instead open a drawer (Exact scenarios when this is useful might need to be defined)

Start by locating the drilldown action and drilldown view entry points in the repository, then review how existing navigation or panel-opening behavior is implemented. Define the drawer use cases and expected behavior before identifying the affected components and tests; the issue currently names no files or acceptance criteria.
