    Install "pyroute2" as a doc job depedency

    By adding this library to the doc requirements file, tox will install
    it limiting the upper version according to
    "requirements/upper-constraints.txt".

    "pyroute2" is called in tox doc job as mentioned in [1]. Since version
    0.6.0, the library structure changed. To keep backwards compatibility,
    all modules are imported from the main namespace. As reported in the
    referred bug, the library "mitogen" must be installed first.

    In stable releases that use older "pyroute2" versions, this library is
    not needed but this patch should enforce the upper library version.
