In Scope

• Ensure that API for steps, stages and parallels reflects the "aborted" state when a step is aborted
• When the Pipeline is aborted the stage & parallels shows up as failed. The stages & parallels should show up as aborted.
• When the Pipeline is aborted the executing steps show up as failed. The steps should show up as aborted.
• One this is completed, test that this works in the UI. If it does not work open a GUI ticket for updating it to handle the ABORTED state correctly.

Notes
svanoort has provided some technical details

Note that at least for stage, there is no result set. I aborted a build (kzantow/failure-project "passing" branch) and I saw the following:

{
"_class": "io.jenkins.blueocean.rest.impl.pipeline.PipelineNodeImpl",
"_links": {},
"actions": [],
"displayName": "Archive",
"durationInMillis": 0,
"id": "9",
"result": null,
"startTime": null,
"state": null,
"edges": []
}

Which is not correct.
