BUG/MEDIUM: stats: Eat output data when waiting for appctx shutdown

Browse source 
When the stats applet is executed while a shut is pending, the remaining
output data must always be consumed. Otherwise, this can prevent the stream
to exit, leading to a spinning loop on the applet.

It is 2.8-specific. No backport needed.
