    Moved out common testcases from test_type_vxlan.py

    This patch-set will refactor the test_type_vxlan.py and test_type_gre.py.

    We need to add testcases for TunnelRpcCallbackMixin() so better we
    should move common test cases from test_type_vxlan.py to test_type_tunnel.py and
    add testcases for TunnelRpcCallbackMixin() into it.
