Which case for FCCT

[ajeddeloh]

The Fedora CoreOS Config Transpiler (FCCT) will read FCCs and emit Ignition configs (see #129). This mirrors how with Container Linux is configured with CLCs and the Container Linux Config Transpiler (CLCT).

Ignition uses camelCase in it's config currently. CLCT uses snake_case. We should pick one for FCCT.

I'm not what will be more confusing: using a different case than Ignition or being different than CLCT.

Worth calling out we can change Ignition with a major spec bump, but that's a lot of churn and I'd like to avoid it if possible.

From the meeting today jonathan and I both had this opinion:

a slight preference for dash-case overall, but between camelCase and
snake_case i'd rather the latter

[ajeddeloh]

FWIW I also prefer snake case, though very weakly. Talking with @crawford he thinks using snake case with yaml and camel case with json is pretty standard. Snake case also is also what cloudinit uses, so that's a tiny bit less friction for those coming from cloudinit-land.

I'm going to close this out in favor of snake case by EOD friday if no one has a strong case the other way.
