If the runtime passes a pod UID via K8S_POD_UID (which both CRIO and
containerd do as of mid-2021) then fail if the pod we get from the
Kube API has a different UID. This would indicate that the pod was
deleted and recreated while Multus was attempting to set up
networking for the old pod instance's sandbox, and it's pointless
to continue setting up a sandbox for a dead pod instance.
Also pass the pod UID through to plugins so they can perform
additional checking and validation on the pods they get from the
Kube API.

Thus not repeating ourselves, nor shadowing the global variables
that had the same name (pollInterval / pollTimeout).

The case withot DeviceInfo/ResourceName, we could skip functions
related to device info. This change skips to call these functions
if delegates does not have DeviceInfo/ResourceName.
