Cronjob pods matched by deployment, pdb and service selectors
Cronjob pods currently have labels that are matched by the service deployment's selector, the pdb's selector as well as the service's selector.
This leads to various problems. For example when a pod spawned by a cronjob is running, it is matched by the service's selector. This causes a certain percentage of requests going through the service to be routed to the cronjob's pod.
