CATs smoke tests should pass

[julz]

This is a catch-all story to cover the first MVP goal of CF Smoke Tests 'apps' test suite passing

Prerequisites:

• We will need to figure out how to deal with the lack of loggregator APIs at this point, possibly by forking the CATs to allow the logging to be done directly via kubectl get logs or similar.

Acceptance:

1. Follow instructions on smoke tests repo pointed at a CF deployed with eirini (following instructions on eirini repo for this), they pass, weeee!
