fiber switch support for huawei switch

[Miles Fu]

The commands for some huawei switch like CE6850EI does’nt suit the code in huawei.py.
It needs to execute the command 'commit' after configing the port or network.
So, I want to add a new device for this type of huawei switch.

    add support for huawei VRPV8 switch.

    detail:
        Huawei switch like CE6850EI needs to execute the command 'commit'
        after configuring the port or network. And also add the unit test for
        this type of switch.
        All newest huawei devices use VRP v8 as the next network OS now. For
        VRP v8 platform, the command 'commit' is used to avoid making some
        mistakes in a ssh connection.
