plugin/ryu: update for ryu update
blueprint ryu-plugin-update-for-ryu Now ryu has GRE tunnel support, so update ryu plugin to support it. This implements/simplifies GRE tunneling support for ryu plugin Change-Id: I158affcb60c9016753dbbbf5f1ad50286af49c23 Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
