pauseRequestsRecursive

Performs pauseRequests recursively for all managers that are contextually descendant to this manager based on the Activity/Fragment hierarchy:

• When pausing on an Activity all attached fragments will also get paused.
• When pausing on an attached Fragment all descendant fragments will also get paused.
• When pausing on a detached Fragment or the application context only the current RequestManager is paused.

Note, on pre-Jelly Bean MR1 calling pause on a Fragment will not cause child fragments to pause, in this case either call pause on the Activity or use a support Fragment.
