Bug description:
  [Impact]

   * Curtin doesn't support multiple derived archive/repositories with
     custom keys as typically deployed in an offline Landscape deployment.
     Adding the custom key resulted in an error when processing the
     apt_source configuration as provided in this setup.

     Curtin has been updated to support the updated apt-source model
     implemented in cloud-init as well.  Together the existing Landscape
     deployments for offline users can now supply an apt-source config
     that updates curtin to use the specified derived repository with a
     custom key.
     
  [Test Case]

   * Install proposed curtin package and deploy a system behind a
     Landscape Offline configuration with a derived repo.

    PASS: Curtin will successfully accept the derived repo and install the
          system from the specified apt repository.

    FAIL: Curtin will fail to install the OS with an error like:

    W: GPG error: http://100.107.231.166 trusty InRelease:
    The following signatures couldn't be verified because the public key
    is not available: NO_PUBKEY 2C6F2731D2B38BD3
    E: There are problems and -y was used without --force-yes

    Unexpected error while running command.
    Command: ['chroot', '/tmp/tmpcEfTLw/target', 'eatmydata', 'apt-get',
              '--quiet', '--assume-yes',
              '--option=Dpkg::options::=--force-unsafe-io',
              '--option=Dpkg::Options::=--force-confold', 'install',
              'lvm2', 'ifenslave']
    Exit code: 100
    

  [Regression Potential]

   * Other users of previous curtin 'apt_source' configurations may not
     continue to work without re-formatting the apt_source configuration.

  
  [Original Description]

  In a customer environment I have to deploy using offline resources (no
  internet connection at all), so I created apt mirror and MAAS images
  mirror. I configured MAAS  to use the local  mirrors and I'm able to
  commission the nodes but I'm not able to deploy the nodes because
  there is no way to add gpg key of the local repo in target before the
  'late' stage'.

  Using curtin I'm able to add the key but too late, in fact  according
  with http://bazaar.launchpad.net/~curtin-
  dev/curtin/trunk/view/head:/curtin/commands/install.py#L52 "late"
  stage is executed  after "curthooks" this prevent to add the key.

  I checked also apt_config function in curthooks.py  I did't see code
  that add the key for each mirror.

  It should be possible to add gpg public of the repository in maas.
