Create Cloud Shell Tutorial

[josephlewis42]

It would be really cool to re-format the docs into a single start-to-end tutorial that could be run in Cloud Shell. It would make the multi-hour instillation more bearable (because the sidebar would keep track of where you were) and would make it harder to skip steps.

@josephlewis42 I know one PR on this topic has been merged. What is this issue's status?

I think this is still open. My thought was to allow users landing on the gcp-pcf-quickstart homepage to click a button and launch the full PCF install process.
