    Fix sanity check --no* BoolOpts

    If --config-{file,dir} are used to genearate a list of tests to
    run, using set_override() will also override any options passed
    via the CLI.

    For example, on Centos 7 which uses dnsmasq 2.66, running:

      neutron-sanity-check --nodnsmasq_version --config-file \
        /etc/neutron/l3_agent.ini

    will still run and fail the dnsmasq version test. Using
    set_default() allows using --config-{file,dir} and --no* in
    conjunction.
