This patch does two things:
1. We modify the restar policy from never to "OnFailure" for the
Importer (we already did this for Upload, and we don't want to do it yet
for the Clone pods)
2. Upon succesful completion delete our worker pods
We're not doing this on failed pods right now because in general an
admin will likely want to inspect the pod to see why it failed.
The first question someone will likely ask is "well what about a node
failure", well in the case of a node failure for CDI we have a bigger
outstanding issue remaining to figure out how to deal with volume
connections. We can't just simply reschedule the job.
