DCO enforcement for all OpenInfra Foundation repos

Opendev hosts a number of repositories for OpenInfra Foundation
efforts which are not themselves Open Infrastructure Projects. These
repositories were enforcing the old foundation CLA which is no
longer valid. After consulting the foundation's executive
management, it was decided they should use the DCO instead like
Airship/Kata/OpenStack/StarlingX are already doing.
