Outline View: add action buttons

[josephjclark]

• execute this workflow
• debug this workflow?
• edit this workflow?
• delete this workflow? (cascading)

1. Do we need edit? because clicking the workflow in the treeview opens it. which basically is edit.
2. Is the delete functionality here basically deleting all things related to the workflow? the job files related to it and so on? like a cascading delete.

Keep it simple for now, let's just do the things that immediately make sense (execute).

The notes are just me thinking ahead in the moment to what might be useful later. :) If none of them make sense, then no problem

Yes, I think delete would be a cascading delete - remove the workflow json and all job files. But we don't need to implement this now.
