    Set upper boundary for python-ceilometerclient

    Set upper boundary for python-ceilometerclient with version of the
    package contained in fuel-infra repositories. This eliminates the issue
    with dependency conflicts but is not permanent solution.

    Dependency conflicts are due to dyssynchrony of the package versions
    from the OpenStack global requirements and packages contained in our
    repository.
