Alex Vandiver 7c8eacfa12 queue: Increase paging thresholds for deferred_work queue. ...

This queue is used to things which definitionally may take longer than
a request, so paging after 60s is rather aggressive.  This is
especially true because this queue has a very long tail of very slow
tasks -- p99 of task time in this queue is 8.5s, while p99.9 is 197s.

Raise the paging threshold to 15 minutes.  While there are
semi-user-facing tasks which use this queue (primarily marking
messages as read), those being delayed for minutes is already a real
possibility if they are stuck behind a large realm export -- and this
is not a situation which should necessarily page, since it is not
solvable by the administrator.
