Investigate what k8s information a Pod can retrieve about itself

[bbengfort]

In #53 we created a peers mechanism for directory service replication that requires information about PID, name, and region. This information can be configured, but that would require a per-pod stateful set, which is less than ideal. So the question is, can the Pod retrieve information from k8s about itself, e.g.PID/name - perhaps even region? Is there a way to create an operator so that the spec template is modified to provide these details on a per pod basis?
