kolla tries to install python2-cffi but latest version is python-cffi in base

[Alfredo Moralejo]

When trying to build containers with RDO/CentOS and binary type, it fails to build openstack-base with error [1]:

INFO:kolla.image.build.openstack-base: * updates: denver.gaminghost.co
INFO:kolla.image.build.openstack-base:1 packages excluded due to repository priority protections

INFO:kolla.image.build.openstack-base:Error: Not tolerating missing names on install, stopping.
INFO:kolla.image.build.openstack-base:

Note that latest version of python-cffi is provided from CentOS base and is python-cffi instead of python2-cffi.

According to CentOS/RDO packaging rules, all python2-XXX packages has a provides on python-XXX, so when installing it, python-XXX should always be used as it will install the right package.
