cloud: Add console kargs

[cgwalters]

This is important for debugging things.

We should be able to ship this now that containers/bootc#206 landed!

Oh man, TOML files to describe kargs is incredible!

Just a sanity check...is this a bit of sarcasm? I am not totally sure.

Having kargs in TOML already exists in blueprints as [customizations.kernel] for example.

I know bootc's install config duplicates this (and kickstart, and Ignition, and $long_list_of_things) but my idea so far is to keep the bootc config to an absolute minimum of bootstrap things that are desirable cross-distribution. (And also bootc install can work outside of Anaconda/ImageBuilder/etc.)

We'll also aim to support embedding blueprints in the container image metadata.

No, definitely not. I look forward to this more declarative approach for defining the OS.

Text is hard! Sorry for the confusion.
