Job sidecar termination service.

Public domain software. Original code by Henrik Holst [email protected].

Pending the availability of an upstream solution:

kubernetes/enhancements#3580

The service will send a SIGTERM to all processes once all containers has terminated, that is not included in the exclude list. The exclude list is simply the arguments given to the Service itself.

This requires shareProcessNamespace: true on the Pod.
