    Add missing dependencies (from pip-missing-reqs)

    Any explicit imports we have in magnum, we should specify
    the pypi package version number in our requirements. The
    pip-missing-reqs helps us find these.

    Note that python-dateutil is an optional import in
    the python-k8sclient AND it's not in the global requirements
    so not adding that.

    Here are the references to the imports for the packages
    we are adding here:
