/**
* Support of restarting failed stages or steps in a pipeline is limited in Jenkins.
*
* This has been documented in the [Jenkins Jira issue JENKINS-33846](https://issues.jenkins-ci.org/browse/JENKINS-33846).
*
* For declarative pipelines there is a solution available which partially addresses this topic:
* https://jenkins.io/doc/book/pipeline/running-pipelines/#restart-from-a-stage.
*
* Nonetheless, still features are missing, so it can't be used in all cases.
* The more complex Piper pipelines which share a state via [`commonPipelineEnvironment`](commonPipelineEnvironment.md) will for example not work with the standard _restart-from-stage_.
*
* The step `pipelineRestartSteps` aims to address this gap and allows individual parts of a pipeline (e.g. a failed deployment) to be restarted.
*
* This is done in a way that the pipeline waits for user input to restart the pipeline in case of a failure. In case this user input is not provided the pipeline stops after a timeout which can be configured.
