Use kubernetes Garbage Collection to simplify resource management

[godber]

Use k8s GC to make sure all of the k8s resources related to a job get cleaned up on job execution.

The role of the Kubernetes garbage collector is to delete certain objects that once had an owner, but no longer have an owner.

You can also specify relationships between owners and dependents by manually setting the ownerReference field.

Not sure if I should make a CRD that has all three of the as the owner of the job (sounds cleanest, but not sure what would be implied by creating a CRD and not doing anything else with it).

Alternatively I could use one of the existing resources as a parent and the others children.
