Title:
  Autoupdate should be less frequent and more randomly distributed

Status in Snappy:
  Fix Released
Status in snapd package in Ubuntu:
  Fix Released
Status in snapd source package in Xenial:
  Fix Released

Bug description:
  Currently the autoupdate timer (snappy/debian/snappy-autopilot.timer)
  is set to hourly with a 15 minute accuracy.

  As snappy will be included in 16.04 desktops (millions of them), this
  rate has the potential to seriously overload the Click Package Index
  service. I suggest changing this to 3 times per day, randomly
  distributed across 24hr on a per host basis so we don't get top-of-the
  hour thundering herds.

  Further rationale is to also avoid having updates downloaded by all
  hosts within the first hour of release, since gradual/staged updates
  are not implemented for snaps.
