support admin-state of port

[Li Ma]

currently admin-state is not supported for port updating.

for example, in selective distribution:

https://github.com/openstack/dragonflow/blob/master/dragonflow/controller/topology.py#L45

It should check whether port's admin-state-up is true or false. We need to support the state changing from true to false and from false to true as well.

why do detemine in https://github.com/openstack/dragonflow/blob/master/dragonflow/controller/topology.py#L45, not in https://github.com/openstack/dragonflow/blob/master/dragonflow/controller/df_local_controller.py#L191?

port's admin-state-up will be updated by neutron-server, not by nova or l3-agent, which will call ovs_port_updated(), for example, nova will create an ovs interface when create vm, this is my understand maybe wrong, : )

sorry for misunderstanding. i used a wrong verb, not 'determine', but 'check'. i just give an example, not implementation. port's admin-state-up can also be changed via api, afaik.
