Implemented readinessProbe in l2sm-controller Deployment and added initContainers in l2sm-operator Deployment to ensure proper synchronization with l2sm-controller pod status before starting.

This change ensures that l2sm-operator does not start until l2sm-controller pod is in the Running state.

general: added bridge interfaces between switches and pods. \n This is with the objective  of easing and automating the installation of l2sm, without having the user to configure the ip addresses in their machine
