@MikeThomsen Thank you for your review! I think I tested it fairly well
also, so with your +1 I can merge this in.

> ExecuteStreamCommand only has a success relationship. The gist is it
> executes the command, captures the output stream, code, etc.. and stores the
> necessary content and attributes.
> However, for those wanting to see the status code as an indicator of failure
> they have to create a flow which checks, loops, etc.. This is more work than
> necessary since the processor can provide a better indicator. By adding a
> failure relationship we can route results and status codes for non-zero to
> this relationship. We'll have to consider backward compatibility friendly
> ideas but the gist is to make this common failure/retry pattern easier to
> configure and track.
