Right now the compose can only be identified by a compose ID. That is generally unique and nice, but can be hard to work with.

We should include separate fields for release short, name, version, and type, and compose date, respin, type and label.

This data is probably not available for the fail-to-start message, but it's not such a big deal there.

Currently if someone wants that information, they either have to bend over backwards to parse it from compose ID or download metadata.
