Problem:
Currently, the katacoda tutorials are embedded in the kubernetes website. The majority of the issues that get opened toward those tutorials are support requests, rather than issues against the documentation. Currently, these tutorials are also hosted elsewhere in the org, and this has raised the question about how to handle dual hosted content.

Proposed Solution:
Lazy consensus is that we remove the katacoda tutorials and link to them somewhere in the in the docs. Possibly the top level page that explains the tutorial.
