Distributed datapath for metadata

Registered by LIU Yulong

When instances are booting, they will try to retrieve metadata from Nova by the path of Neutron virtual switches(bridges), virtual devices, namespaces and metadata-agents. After that, metadata agent has no other functionalities. In large-scale scenarios, a large number of deployed metadata agents will cause a waste of resources for hosts and message queue. Because metadata agents will start tons of external processes based on the number of users' resources, report state to Neutron server for keepalive.

We are going to implement an agent extension for Neutron openvswitch agent to make the metadata datapath distributed.
