tripleo-repos rpm can't be installed on centos 7

[Ben Nemec]

As of https://review.rdoproject.org/r/#/c/17875 python2-tripleo-repos depends on python2-requests. However, CentOS 7 doesn't have python2-requests, it has just python-requests. This makes tripleo-repos uninstallable without hacking around the dependency problem.

To reproduce, run "yum install https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-0.0.1-0.20181218124416.a5b709e.el7.noarch.rpm" on a CentOS 7 system. It will fail with:

Error: Package: python2-tripleo-repos-0.0.1-0.20181218124416.a5b709e.el7.noarch (/python2-tripleo-repos-0.0.1-0.20181218124416.a5b709e.el7.noarch)
           Requires: python2-requests

Note that python-requests is already installed on the system (at least in my case), so this can be worked around by doing a direct rpm --nodeps install.
