MB-7090: refresh stats dictionary on change in stat keys

I.e. when there's new xdcr or view which stats should be displayed. Or
when xdcr or view is deleted. In this case we'll detect it and trigger
refresh of stats dictionary. Which due to magic of cells will
automatically redraw stats adding or removing graphs as needed.
