Bug description:
  [Impact]
  On the Ubuntu One File Storage API we see a big spike in the number of API requests at 00:00Z, daily. Pretty much all of the requests at that time come from Deja Dup/Duplicity.

  This makes it more likely that users will see errors from Ubuntu One
  being overloaded, like in bug 882699.

  [Fix]
  Due to a bug, we always were backing up at midnight UTC, rather than midnight local time.  While fixing that, I also put in code to randomly choose a time between 2 and 4 AM (local time), rather than midnight.

  [Test Case]
  * Enable daily automatic backups
  * Change your time zone so that it is 2AM
  * Wait two hours.  Deja Dup should start backing up within those two hours.

  [Regression Potential]
  * The only code changed was the automatic scheduler.  So any regressions would be there.
