    Add devstack local.conf sample for ML2 OVS

    Since devstack had set OVN as the default backend for Neutron.
    Then the minimum local.conf [1] for ML2 ovs will not work at
    all. For some local testing of ML2 OVS, it is not right deployment
    for users to test the ML2 OVS related cases.

    This patch adds a sample local.conf for ml2 ovs to install a small
    all in one environment for Neutron testing.

    Sample tested OS:
    1. CentOS Stream 8
    2. CentOS Linux 8
