Certain steps should always fail, even though resilience option `failOnError=false` is used.
* Docker execution typically happens in another step. We should not hide errors here but rather handle their resilience in the step which uses `dockerExecute` and `dockerExecuteOnKubernetes`.
* Wrapper steps like `pipelineExecute`, `pipelineRestartSteps` should not hide errors. If an error occured this has to be considered as **intentional** and not hidden accidentially in case resilience option is switched on.
In case there is an error in another pipeline step inside a foreign pipeline we got
nevertheless an error explaining there is an issue inside the pipeline load step.
