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

Directly create bootable volume based on image ID.

Now that a bootable volume can be created directly based on
image ID, we can dispense with the complexity around using
a builder instance to acheive the same effect.

Install the python-netaddr package before we use it.

It's used if installed and not used if not installed, which is confusing.
So trying to install it should make things a bit less confusing.

It's available under the same name in both Fedora and Ubuntu.

clear screen rc file every time you run stack.sh

fixes bug 1032022.

Devstack will not update service's start up command if the command already
exists in screen rc files due to previous deployment. There is no way to
clear a service's start up command so this would be a problem if the service's
start up command changes between different deployment. Clear the content of
screen rc file every time you run stack.sh to deploy openstack can solve
this problem.

Modify nova config for ceilometer if enabled

If ceilometer is enabled, nova instance usage auditing and the
appropriate notification drivers should be automatically enabled,
as opposed to relying on manual reconfiguration and service restart.
