Removed pip requirements from the repo-server role

The pip requirements in this role are not needed to stand up the
repo-server. Being that they're not required they should be removed.
The needed bits used to build the python wheels will be re-added to
the repo-build role where it can leverage the cloned upstream upper
constraints file from the openstack global requirements repo.
