python-urllib3-1.10.2-7.el7.noarch was supposed to be removed but is not

Issue

• Doing a yum upgrade on a node (in the case masters) results in failure due to a conflict with a urllib3 (eventually installed with pip). I would expect that yum is smart enough for this not to occur, or that we identify and remove where urllib3 is installed otherwise, so that these conflict does not emerge and a yum upgrade is run cleanly.
