FlowRule private extension refactor. 

1.merge private flow into regular flowrule subsystem.no mirror code any
more.no change flowrule api.
2.define a rich-data-type to carry private flow.
3.modify OpenFlowRuleProvider.class to support for 3rd party private
flow.i don't know whether is suitable.because this class name is
relative with open flow protocal.
4.fix some junit test bug caused by modification of FlowRule interface.
