ExecutorStep adds a WorkspaceAction to track the fact that the flow build used a workspace, and if you navigate the flow graph UI you can get to a workspace browser, but there is not much more than that available. Need:
- Analogue of noWorkspace.jelly in case a workspace cannot be loaded
- Nicer DirectoryBrowserSupport.title: WorkflowRun.getFullDisplayName, computer, path, ...
- Functionality similar to doDoWipeOutWorkspace, though see JENKINS-4646 and related issues
- FlowNodeViewColumn or other way of seeing a list of workspaces for a build (or for the last build of the project)
