use C3I-as-a-Service to allocate a dynamic project for building and testing
The C3I-as-a-Service system (https://pagure.io/c3i-library/blob/master/f/c3iaas)
enables creation of new OpenShift projects, which will be deleted after a
configurable period of time, and are suitable for building and testing proposed
changes. The MBS-Koji integration tests now make use of C3IaaS, to reduce resource
contention and avoid false failures due to quota limitations.
