Currently, ryu-manager uses distutils.version.LooseVersion for "--zapi-frr-version" to parse the given version sting. With custom type class for oslo_config.cfg.Opt, oslo_config might access __class__ attribute for equal comparison. But in case on Python 2, LooseVersion does not have __class__ attribute and it causes AttributeError. (This error is not always reproduced) This patch injects required attribute into LooseVersion and avoids this problem.
