Add registry role to ansible

[DanielKuzmenkoo]

I want to add the option to add a role that will set up a private registry, so there will be an option to both registry and tarball.

@DanielKuzmenkoo are you looking to run a private registry, in Docker perhaps, locally that you can point to? RKE2 allows you to specify an overwrite and/or mirror that will point to an existing private registry.
