WHAT

🤖 Generated by Copilot at 4aa324c

This pull request adds a new feature to support NetworkManager on Linux nodes by creating a networkManagerSyncer type that syncs network configuration between NetworkManager and OVS bridges. It also refactors the controller code to use receiver methods instead of global functions for provider network initialization and cleanup, improving modularity and testability. The changes affect the files pkg/daemon/controller_linux.go, pkg/daemon/controller.go, pkg/daemon/init_linux.go, pkg/daemon/init.go, pkg/daemon/ovs_linux.go, pkg/daemon/init_windows.go, and pkg/daemon/nm_linux.go.

We added a new type and a syncer
We also refactored
The controller methods
And used receivers instead of global handler

HOW

• Add a new type networkManagerSyncer and its methods to handle the synchronization of network configuration between NetworkManager and OVS bridges on Linux nodes (link)
• Add a field nmSyncer *networkManagerSyncer to the Controller struct to store a reference to the network manager syncer instance (link)
• Initialize and run the network manager syncer in the initRuntime function of the controller (link)
• Refactor the functions ovsInitProviderNetwork, ovsCleanProviderNetwork, configProviderNic, and changeProvideNicName to use the receiver c *Controller instead of global functions, making the code more modular and testable (link, link, link, link, link, link, link, link, link, link)
• Remove the unused import statement and function nmSetManaged from the file pkg/daemon/init_linux.go as they are no longer needed (link, link)
• Remove the redundant code to configure the provider NIC in the InitOVSBridges function as it is now handled by the network manager syncer (link)
• Set the provider NIC unmanaged by NetworkManager and add it to the network manager syncer in the configProviderNic function (link)
• Use the network manager syncer instance to set the provider NIC managed or unmanaged by NetworkManager in the changeProvideNicName function (link)
