To support metadata service, neutron-ns-metadata-proxy is baked into the controller image. Also neutron-metadata-agent startup script (/etc/init.d/neutron-metadata-agent) and config file (/etc/neutron/metadata_agent.ini) are added to start up metadata agent at system initialization. dhcp_agent.ini and nova.conf are updated as well. A README.metadata is added in the Documentation/ directory. Signed-off-by: Andy Ning <andy.ning@windriver.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
