feat: add custom config support to talosctl cluster create

[utkuozdemir]

Allow passing a static, custom config to every machine created by talosctl cluster create. This is useful for testing, e.g., passing partial machine config via cloud user data.

We should probably plan later to support a config file like kind, we have too many options 😅

(thinking about having less flags)

would it work if we re-use inputDir flag, and pass same controlplane.yaml/worker.yaml without talosconfig ? (and add handling for empty talosconfig?)

Yep, I thought about it as well. The main reason to go this way was to be able to pass small configs directly as flags instead of as files. Also they have a less change of being different across control plane and worker. Creating a directory structure to meet this need felt a bit too much for this use case.

I think this is more convenient to use, but I can change, no problem.

Changed it to be that way, hence got significantly simpler.
