Add sugar for `.container` systemd quadlet units about butane HOT 5 OPEN

Moving back to Butane.

from butane.

Quadlets are "just" files in /etc/containers/systemd/ so there is nothing to add in Ignition. Butane could grow some validation logic but not usre how much that would be useful / comprehensive.

For what it's worth, I also ran it into this just now. It still occurs when using target.container as the unit name.

This happens because quadlet are not systemd units, so you can not use this syntax to set them in Butane.

See https://github.com/travier/fedora-coreos-matrix for an example config using quadlets.

Yeah, makes sense. Thanks for the example config.
