Pull #3462

github

Summary of changes: * Implements controllers for Admin Policy Based External Route to handle changes to namespaces, pods and admin policy based external route CRs. Initialize in master node to handle interactions with the north bound DB. Initialize in worker nodes to handle changes to the conntrack (delete ECMP entries when a gateway IP is no longer a valid external gateway IP) * Implements repair() function for the master node. * Integrates with the annotation logic to avoid duplications in cache by sharing the externalGWCache and EXGWCacheMutex objects between the annotation and controller logic. * Updates the annotation logic to ensure the namespace anontation k8s.ovn.org/external-gw-pod-ips is updated when changes occur in a CR instance that coexists in the same namespace and that can impact the list of dynamic gateway IPs. * The implementation no longer relies on namespace annotations, including "k8s.ovn.org/external-gw-pod-ips", instead it uses its own cache structure to identify the valid pod IPs for a given namespace. * Implement E2E tests for admin policy based external route. The tests are a duplication of the existing annotated based logic for external gateways using the CR instead.
