Bug description:
  === Begin SRU Template ===
  [Impact]
  New feature to validate and log invalid schema warnings from cc_ntp cloud-config module.

  [Test Case]
  if [ ! -f lxc-proposed-snapshot ]; then
    wget https://git.launchpad.net/~smoser/cloud-init/+git/sru-info/plain/bin/lxc-proposed-snapshot
    chmod 755 lxc-proposed-snapshot
  fi

  cat <<EOF > valid.conf
  #cloud-config
  ntp:
  EOF
  cat <<EOF > invalid.conf
  #cloud-config
  ntp: -1
  EOF
  for release in xenial zesty; do
          ref=$release-proposed;
          echo "$release START --------------";
          ./lxc-proposed-snapshot --proposed --publish $release $ref;
          lxc init $ref test-$release;
          lxc start test-$release;
          sleep 10;
          lxc exec test-$release -- sudo apt update;
          lxc file push valid.conf test-$release/valid.conf;
          lxc file push invalid.conf test-$release/invalid.conf;
          lxc exec test-$release -- python3 /usr/lib/python3/dist-packages/cloudinit/config/schema.py -c /valid.conf | grep Valid;
          lxc exec test-$release -- apt-cache depends cloud-init | grep jsonschema # should be empty;
          # invalid.conf will not generate errors when jsonschema is not present
          lxc exec test-$release -- python3 /usr/lib/python3/dist-packages/cloudinit/config/schema.py -c /invalid.conf | grep invalid;
          lxc exec test-$release -- sudo apt install python3-jsonschema
          # invalid.conf *will* generate errors when jsonschema is not present
           lxc exec test-$release -- python3 /usr/lib/python3/dist-packages/cloudinit/config/schema.py -c /invalid.conf | grep invalid;
  done;

  [Regression Potential]
  We don't want to introduce a mandatory jsonschema dependency in older series.
  Validate that older releases can run without errors when jsonschema is *not* installed.

  === End SRU Template ===

  cloudinit needs a mechanism to parse and validate a strict schema
  definition for modules that parse user created #cloud-config yaml
  files.
