test tool: add a script to make the test environment on mininet

What this patch implements:

    This patch implements a script that provides the simple test environment that includes 2 switches and 2 links for the test tool as follows:

                      +-----------+
           +----------| target sw | The OpenFlow switch to be tested (Open vSwitch)
           |          +-----------+
    +------------+      (1)   (2)
    | controller |       |     |
    +------------+      (1)   (2)
           |          +-----------+
           +----------| tester sw | OpenFlow Switch (Open vSwitch)
                      +-----------+

      (X) : port number

How to run:

    Do the following command:
    sudo ryu/tests/switch/run_mininet.py

    And then, run the test tool at another terminal:
    ryu-manager ryu/tests/switch/tester.py
