func (*Engine) UpdateNetworkContainers 

func (e *Engine) UpdateNetworkContainers(containerID string, full bool) error

UpdateNetworkContainers updates the list of containers attached to each network. This is required because the RefreshNetworks uses NetworkList which has stopped returning this information for recent API versions. Note that the container cache is used to obtain this information, which means that if the container cache isn't up to date for whatever reason, then the network information might be out of date as well. This needs to be considered while designing networking related functionality. Ideally, this function should only be used in the refresh loop, and called AFTER RefreshNetworks() because RefreshNetworks() will not populate network information correctly if container refresh hasn't taken place. The containerID argument can be provided along with a full argument can be used to limit the update as it concerns only one container instead of doing it for all containers. The idea is that sometimes only things about one container may have changed, and we don't need to run the loop over all containers.
