Bug description:
  Impact
  ------
  An Ubuntu system will unexpectedly reboot if reboot-required exists and you run unattended-upgrades in dry-run mode.

  Test Case
  ---------
  1) modify /etc/apt/apt.conf.d/50unattended-upgrades so that Automatic-Reboot is true
  2) Ensure all updates are installed
  3) sudo touch /var/run/reboot-required
  4) run 'sudo unattended-upgrades --dry-run'
  5) watch the system reboot

  With the version of unattended-upgrades from -proposed the system will
  not reboot.

  Regression Potential
  --------------------
  This checks to see if the --dry-run switch is passed to unattended-upgrades before calling the reboot function. I guess it would be a regression to people who expect the system to reboot but that seems like a very strange corner case.

  Original Description
  --------------------
  Much to my surprise, when I did a dry-run test of unattended-upgrades my server was forcibly rebooted. I must have had the file '/var/run/reboot-required' present.

  But needless to say: a --dry-run should NOT perform a reboot of the
  server with zero warning. Seriously.

  Output from /var/log/unattended-upgrades.log

  Version: 0.76ubuntu1

  As an aside, it makes a lot of sense to me to put the reboot on a
  timer, even if it's only a one minute (i.e. shutdown -r 1). That would
  have at least given me a chance to prevent the reboot if I had seen
  the warning. If that's a configuration setting I don't see it
  anywhere.
