NetworkPort objects are now attached to the NSController (not individual containers).
The NSController manages the network namespace for the entire pod, and containers
within that pod share this network configuration. This design allows containers
to share the same network stack while maintaining proper isolation via the
NSController's network namespace.
The refactor consolidates network port creation by:
- Scanning all containers in a pod to collect network requirements
- Creating NetworkPort records attached to the NSController
- Updating port_type from "container" to "nscontroller"
- Removing explicit networks configuration from NSController config (relying on inherited pod networking)
