[CP-7738] attempt to publish the workload name of a pod

[dmepham]

Description of the issue

Currently, the addPodOwnersAndPodName method attempts to find the "pod name" of from the OwnerReferences attribute of a pod and sets the PodName tag accordingly. If the pod is from a statefulset, the PodName is set as the actual pod name. If the pod is from some other type of workload resource, PodName is set to the name of that workload resource. If the pod is from kube-proxy, that PodName is set to "kube-proxy". if no name can be found from previous conditions, the PodName is set to the Name attribute of the pod.

The issues with this is that setting PodName to the name of the workload resource that controls it is inaccurate. It is also inconsistent, because statefulset pods are set to the name of the statefulset pod.

Description of changes

This PR alters this method to instead set a new tag, WorkloadName, and removes the special case for statefulsets. This means that a WorkloadName and PodName tags will exist. WorkloadName should be the name of the workload resource from the pod, or an empty string if it cannot be determined. podName should be the actual name of the pod.
