Add support for the Quantum Ryu plugin.
This patch allows using the Quantum Ryu plugin.
Ryu plugin lets Quantum link Open vSwitch and Ryu OpenFlow controller[1].
Ryu OpenFlow controller is not Openstack component, but I added some
processing that is related with Ryu to stack.sh for the convenience of
the person who intend to try the plugin.
Instructions for using Ryu plugin:
1. Enable services: "q-svc", "q-agt", "q-dhcp", "q-l3", "quantum", "ryu"
2. Set Q_PLUGIN to "ryu"
3. Set an internal network interface name to connect br-int on plural
hosts to RYU_INTERNAL_INTERFACE (optional)
Example localrc:
disable_service n-net
enable_service q-svc q-agt q-dhcp q-l3 quantum ryu
Q_PLUGIN=ryu
RYU_INTERNAL_INTERFACE=eth1
