CHO TEST MONKEY

Summary:
        This is a long-term regression test that is aimed to run for weeks
        at a time. It's goal is to find memory leaks or bugs that otherwise
        cannot be easily seen with short-term tests.
        CHOTestMonkey is the 2016 version of CHOtest. The suffix "Monkey"
        implies both the Chaos Monkey style testing and the year of the
        Monkey 2016.

Topology:
        Att topology - 25 switches and 25 hosts and its structure is
                       designed to simulate a real world configuration.
        Chordal topology - 25 swithces and 25 hosts and because of its
                           chordal graph structure, it's particulary useful
                           in testing the rerouting capability of ONOS.
        Leaf-spine topology - 78 switches and 68 hosts and designed to
                              simulate modern data centers.

Pre-requisites:
        To run out-of-the box this test requires 3 NODES. The cell file
        must be passed through the startup test command, e.g.,

            ./cli.py run CHOTestMonkey onoscell <cell name>.

        Passwordless login must be set from TestStation "sdn" root user.
        This test relies on the topology files to start Mininet located in
        the dependencies/topologies folder. Be sure to check that each
        topology file can be loaded properly by Mininet by using this
        command:

            sudo ~/dependencies/topologies/<topology name>
