Fix neutron-fwaas unit test failure due to mutiple issues.

[Trinath Somanchi]

Due to recent updates to neutron/agents/l3/router_info.py, neutron-fwaas unit tests are failing with the following error.

Also, there are issues with test_varmour_router.py and test_varmour_fwaas.py related to AGENT CONFIG options.

    Fix neutron-fwaas unit test failures due to multiple issues

    neutron-fwaas unit tests are failing due the following issues:

    [1] init parameters of router_info.RouterInfo.
    [2] 'register_process_monitor_opts' in varmour router and fwaas UT.

    This patch fixes those issues.
