> 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.
