Move clear all to recycler view (1/2)

First part of moving clear all button to recycler view.  This CL adds
support in the recycler view adapter for a clear all holder type and
hooks it up to the previous clear all animation.

Adding this breaks several assumptions made externally on the type of
the item and index which will be addressed in the second part.
