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.
