Adds a tooltip (manager) to display tooltips in Controls surfaces. The
manager supports the following:
* The tooltip will not be shown after a certain number of times. Tracked
by a Shared Pref that is passed to the TooltipManager
* The tooltip will be shown pointing to a given position on screen
* The tooltip can be parametrized to show the arrow pointing up
(default) or down.
