Bug description:
  === Begin SRU Template ===
  [Impact]
  Warning message for nova-lxd images in openstack clouds due to no valid datasource found.

  [Test Case]
  # It downloads a cloud image of a given release, and then creates a -proposed
  image with cloud-init upgraded.
  wget https://git.launchpad.net/~smoser/cloud-init/+git/sru-info/plain/bin/lxc-proposed-snapshot
  chmod 755 get-proposed-image

  source novarc

  for release in xenial yakkety zesty do;
   ref=$release-proposed;
   lxc-proposed-snapshot --proposed --publish $release $ref;
   lxc image export $ref .;
   imagefile=`ls -tr *gz | tail -n 1`
   mkdir $ref;
   cd $ref;
   tar -zxvf ../$imagefile;
   cd rootfs;
   tar zcvf $ref.tar.gz *;
   #upload raw image to your cloud
    openstack image create --disk-format raw --container-format bare --file $ref.tar.gz testing/$ref.tar.gz;
    openstack server create --image testing/$ref.tar.gz --flavor=m1.tiny lxd-$release --key-name <your-key>;
    nova floating-ip-create;
    nova foating-ip-associate <server> <address>;
    ssh ubuntu@<address> 'sudo DEBUG_LEVEL=2 DI_LOG=stderr /usr/lib/cloud-init/ds-identify --force 2>&1 | grep Found';   # single datasource: OpenStack
  done

  [Regression Potential]
  Low as this only addresses the warning by correctly identifying the OpenStack cloud datasource.

  
  [Other Info]

  === End SRU Template ===

  
  It seems that signals were crossed in bug 1661797.
  cloud-init implementation reads the environment variable 'platform' from pid1, and nova-lxd implementation exported 'product_name'.

  Thus, ssh to nova-lxd provided container, user sees a warning.
  Also
  $ sudo DEBUG_LEVEL=2 DI_LOG=stderr /usr/lib/cloud-init/ds-identify --force 2>&1 | grep PLAT
  PID_1_PLATFORM=unavailable

  While:
  $ sudo cat /proc/1/environ | tr '\0' '\n'
  product_name=OpenStack Nova
  container=lxc
