Automated Testing of LinchPin

LinchPin has automated testing from PR's (Pull Requests) in GitHub. Whenever a PR is updated or the trigger phrase '[test]' is included in the comment a set of tests will be kicked off. These tests are orchestrated via jenkins in the Centos CI openshift environment.

The point of these tests is to verify that LinchPin works correctly in a variety of different environments. We currently exercise current releases of both Centos and Fedora. On those distros we test the following targets: dummy, duffy, aws and libvirt. We are continuing to expand this.

These distros are provided as containers which are deployed inside the openshift environment.
