KubeOne tooling container prompt breaks

Powerline is limiting the lines to 66 chars and not breaking into a new line. Several approaches and tweaks were tried with no success including setting the COLUMNS and LINES variables.

While this looks more of an issue with powerline, I suggest that we remove it since it's not an essential part of the tooling and this issue confuses the users.
