in either the live-server install, via the ``subiquity`` snap, or the
next generation desktop installer, via `ubuntu-desktop-install` snap.
When "autoinstall" directives are provided in either
``#cloud-config`` user-data or ``/etc/cloud/cloud.cfg.d`` validate
minimal autoinstall schema adherance and emit a warning if the
live-installer is not present.
The live-installer will use autoinstall directives to seed answers to
configuration prompts during system install to allow for a
"touchless" or non-interactive Ubuntu system install.

Schema validation issues currently result in a warning log currently which
can be easily ignored because warnings do not bubble up to cloud-init
status output.
In the case of the live-installer, we want cloud-init to raise an error
to set overall cloud-init status to 'error' so it is more discoverable
in installer environments.
# TODO(Drop this validation When cloud-init schema is strict and errors)
:raise: SchemaValidationError if any known schema values are present.
