Graceful ovs-agent restart

When agent is restarted it drops all existing flows. This
breaks all networking until the flows are re-created.

This change adds an ability to drop only old flows.
Agent_uuid_stamp is added for agents. This agent_uuid_stamp is set as
cookie for flows and then flows with stale cookies are deleted during
cleanup.
