    Validate that python3 is ready for loguserdata

    By default, ubuntu trusty images has python3 executable in
    path, but we can't use that for executing loguserdata script,
    because pkg_resources can't be imported. Now it's proposed to
    try importing pkg_resources for validating readiness of
    python3 for executing this script. If pkg_resources can't be
    imported there is no other choice except using python2.
