Documentation on setting up CHT on k3s

[esthermmoturi]

Per parent ticket: this ticket does not mean adding steps for setting up k3s from scratch. That should be in the prerequisites and just be "set up k3s per our requirements page"

It should be placed under this folder.

@esthermmoturi - this was the old description, but I think it's incorrect - please let me know if I shouldn't have removed this:

This is a generic guide that instructs users on how to install k3s. It should provide an overview and specifications to different components of K3s.

@ernestoteo is hoping to work on this on Monday so please ping me if this needs any corrections.
