I have a couple questions with regards to Harbormaster and our workflow
# I would like to know if it's possible to cancel a harbormaster build when a differential review is abandoned
# Is it possible to send an HTTP request somewhere when said job is cancelled?
# Is it possible to cancel a harbormaster build if a new 'diff' is posted to a differential request? ( In other words; if I post an updated patch, can I just have a rule where the previous harbormaster build is just aborted and the new one goes in its place?)
