[Bug 1667797] [NEW] Need manual control over apt update schedule

[jhansonxi]

Public bug reported:

Xubuntu 16.04 (Xenial)

My ISP is ViaSat Exede satellite service.  They have a monthly data cap
but it doesn't apply during specific time periods.  With my specific
service it is called "Late Night Free Zone" (LNFZ) and occurs between
12:00 and 05:00 in my time zone (it's relative to each subscriber's time
zone).

Currently apt-daily.timer schedules updates at 06:00 and 18:00 according to:
/lib/systemd/system/apt-daily.timer

This unnecessarily wastes MBs of my data cap retrieving updates that
won't be installed outside of the LNFZ anyways.  I would also like to
enable all automatic updates but only within the LNFZ.  But there
doesn't seem to be a way to change the schedule without editing the file
directly and using dpkg-divert to protect it from reverting during
updates.

There needs to be an easier way to change this, either in /etc/default
or /etc/apt, and preferably via front-ends like software-properties-gtk.
