Walkthrough

This change updates a virtual network migration test configuration and implementation. The configuration file removes a remote_host_iface line. The Python source file refactors formatting consistency (quote normalization), adds computation and propagation of remote_host_iface through setup and teardown paths for linux bridge operations, and updates corresponding function calls to pass this parameter. Changes maintain existing functionality while improving code consistency and parameter tracking.
