I rebased it again. Should be all good now.

Excellent job so far @ddebarros . I left some comments which should probably be addressed but I think the main issue at this point is that the tests don't pass yet.

I just noticed that this PR includes a change to a vendor-supplied package. I would think we should not be doing that (certainly not lightly). I misunderstood in earlier conversations. I think we need to understand why this change is necessary and can the goal be accomplished differently.

@joshuaauerbachwatson I created a PR on the openwhisk-client and updated our go.mod file to reflect this change.
