Bug description:
  === Begin SRU Template ===
  [Impact] 
  In work targeted at getting cloud-init into the Ubuntu core image,
  it was noticed that the apt_configure module would fail on Ubuntu core.
  The result was cloud-init reporting failure.

  The changes made were to return early if both:
    a.) there is no 'apt' configuration provided
    b.) there is no 'apt-get' command or the system is snappy.

  [Test Case]
  lxc-proposed-snapshot is 
    https://git.launchpad.net/~smoser/cloud-init/+git/sru-info/tree/bin/lxc-proposed-snapshot
  It publishes an image to lxd with proposed enabled and cloud-init upgraded.

  $ release=xenial
  $ ref=$release-proposed
  $ lxc-proposed-snapshot --proposed --publish $release $ref

  # launch 3 containers 
  #  release-default: no apt config, no files modified. apt_configure module should run.
  #  release-corepass: no apt config, look like ubuntu core. apt_configure should not run.
  #  release-coreapt: apt config, look like ubuntu core. apt_configure should run (and will succeed because this is not core)

  $ apt_cfg=$(printf "#cloud-config\n%s\n" 'apt: {sources: {citest: {source: "ppa:cloud-init-dev/test-archive"}}}')
  $ lxc init $ref $release-default "--config=user.user-data=$apt_cfg"
  $ lxc init $ref $release-coreapt "--config=user.user-data=$apt_cfg"
  $ lxc init $ref $release-corepass

  # create a file that makes cloud-init assume this is core.
  $ for n in $release-coreapt $release-corepass; do
     echo ubuntu-core | lxc file push --create-dirs - $n/etc/system-image/channel.ini; done

  # do not lock default user's passwd (LP: #1679765)
  $ for n in $names; do
     echo "system_info:  {default_user: {lock_passwd: False}}" |
       lxc file push - $n/etc/cloud/cloud.cfg.d/99-nolock-passwd.cfg; done
  # populate /var/lib/extrausers so that adduser --extrausers works.
  $ for n in $names; do
     for f in passwd group gshadow subuid subgid shadow; do lxc file push --create-dirs - $n/var/lib/extrausers/$f </dev/null; done; done

  
  $ names="$release-default $release-corefail $release-coreapt"
  $ lxc start $names
  $ sleep 30

  # expect to see rendering of that file for the default and corefail cases.
  # but not for the
  $ tfile=/etc/cloud/templates/sources.list.ubuntu.tmpl; 
  $ for n in $names; do

  [Regression Potential] 
  Biggest and catastrophic failure would be for the apt-configure module
  to stop running.  That would result in no mirrors being set up and
  no archives added and such.  Such a regression would be caught in
  cloud-init's integration test.

  [Other Info]

  === End SRU Template ===

  1. Zesty
  2. 0.7.9-68-gef18b8ac-0ubuntu1
  3.

  Boot instance with cloud-config like:

  #cloud-config
  apt_configure_enabled: False

  Or

  #cloud-config
  apt_configure:
    enabled: False

  cloud-init would not run the apt_configure config module

  4. cloud-init cc_apt_configure.py does not check whether it's been
  disabled by config
