Bring Redhat support to acceptance tests

OpenStack Infra has jobs to run this on both Ubuntu Trusty and CentOS7.

* Add minitest to Gemfile (dependency to run beaker on centos - see
  http://projects.theforeman.org/issues/2650 for details)
* separate nodepool files to have trusty & centos7 support in OS infra
* spec: add case for repo configuration and support
  RH systems.
