gongysh 00897bd3b7 Add scheduling feature basing on agent management extension
3rd part of blueprint quantum-scheduler

1. Allow networks to be hosted by certain dhcp agents.
Network to dhcp agent is a
many to many relationship. Provide a simple
scheduler to schedule a network randomly
to an active dhcp agent when a network or port is created.
2. Allow admin user to (de)schedule network to a
certain dhcp agent manually.
3. Allow routers to be hosted by a certain l3 agent.
Router to l3 agent is a many to one relationship.
Provide a simple scheduler to
schedule a router to l3 agent if the router is not
scheduled when the router is  updated.
4. Auto schedule networks and routers to agents when agents
start.
5. Only support ovs plugin at this point
