From: John Snow <js...@redhat.com>
When we've reached the concluded state, we need to expose the error
state if applicable. Add the new field.
This should be sufficient for determining if a job completed
successfully or not after concluding; if we want to discriminate
based on how it failed more mechanically, we can always add an
explicit return code enumeration later.
I didn't bother to make it only show up if we are in the concluded
state; I don't think it's necessary.
