PodOwner not found with empty name

Seeing the log `"msg":"error getting pod owner","error":"no pods found with name \"\""` when nginx attempts to connect to the control plane. This is preventing nginx from connecting.


There seems to be an issue where the ContainerInfo provided in the request is empty, so no hostname is found. However, HostInfo is populated.

We should fallback to use HostInfo if ContainerInfo isn't set.
