Filter nodes with propagate: false when evaluating WarningActions

[stuartrowe]

• JENKINS issue(s):
  • https://issues.jenkins.io/browse/JENKINS-70844
• Description:
  • Mark pipeline build step with the downstream build result pipeline-build-step-plugin#107 added a WarningAction to build nodes to allow pipeline visualizers (blueocean, pipeline graph view, etc.) to show the result of downstream builds even if ignored by propagate: false. See https://issues.jenkins.io/browse/JENKINS-70623.
  • As a knock-on this broke post condition sections for declarative pipelines which are using the presence of WarningActions in order to determine which post conditions to evaluate.
  • This fix adds a filter to check if a node has an entry for propagete: false in its ArgumentsAction.
  • This fix is an alternative to Only add WarningAction when propagate: true pipeline-build-step-plugin#110 which skips adding WanringActions when propagate: false.
• Documentation changes:
