Verbose after script on failure

What:

• adds an if statement to run an extra set of commands if the package job fails.
• Currently only runs kubectl get all -A

Why:

• To give package developers some more information about the cluster state when a job fails.

Other Info:

• Had to implement this in a somewhat hacky way since gitlab-ci doesn't support running certains parts of a job on_failure or on_success, an open issue can be found here
