Bug description:
  [Impact]
  In GCE, we want to deploy Ubuntu mirrors per-region.  At the moment, it is impossible to configure cloud-init to look for mirrors with the instance's region substituted in to the mirror DNS name.  This will allow us to do so, which will allow us to improve the experience for Ubuntu users on GCE, both in terms of mirror responsiveness and bandwidth costs.

  [Test Case]
  On GCE, specify a primary mirror search URL of "http://%(region)s.gce.clouds.archive.ubuntu.com/ubuntu/" and run cloud-init. When running 'apt-get update', you should see a mirror URL which matches the above with the instance's region substituted in.

  [Regression Potential]
  There are two existing substitutions for mirror strings: availability_zone and ec2_region.  We will need to ensure that each of these can still be used (testing specifically on EC2 for the latter).

  [Original Report]
  In _get_package_mirror_info (in cloudinit/distros/__init__.py), there is code that specifically handles converting EC2 availability zones to their corresponding regions. This won't work for other clouds that don't have the same form for availability zones (and even if they _do_, they'll have to be configured using strings containing 'ec2'; weird), which is problematic.

  This is particularly a problem for GCE.
