Niels de Vos ab5ca13586 e2e: return useful error message when ConfigMap creation fails
In case the toolbox pod is not available, the error message lists that
no Pods are found, but there is no hint about the toolbox. By mentioning
the toolbox in the error message, it suggests a good place to start
troubleshooting the environment.
