Add metadata service support to controller node
The metadata service is working as the following:
- metadata is being served by nova-api on controller at port 8775.
- VM instance requests metadata by 169.254.169.254 (eg, curl http://169.254.169.254/latest/meta-data)
- metadata request comes to neutron-ns-metadata-proxy on controller in dhcp network name space.
- neutron-ns-metadata-proxy forwards the request to neutron-metadata-agent through a unix domain socket (/var/lib/neutron/metadata_proxy).
- neutron-metadata-agent sends the request to nova-api on port 8775 to be serviced.
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.
