RHOSO 18+ changed the way a cluster is deployed (tripleo -> OCP) and the way tests are executed (direct tempest execution vs test-operator). Both changes significantly affect certification procedures for partners, incl. Networking integration.

This Epic is to implement certification procedure for RHOSO 18+ that would cover both aspects.

The definition of Done here should include:

• a checklist to validate that a cluster provided for certification uses recommended points of integration blessed by Networking DFG;
• a list of test scenarios (tempest, perhaps something else? - need to check what we did before) that must pass for a partner integration to be confirmed as complying;
• documentation updates to relevant guides.

Context:

• There was already a certification program before 18, so it would make sense to adopt the existing approach, if applicable (e.g. the list of tempest scenarios may be directly ported to the new program);
• The checklist doesn't require automation - a cert engineer should be able to follow the instructions though without significant prior knowledge.

Note: this Epic is not supposed to implement actual integration points in service and OpenStack operators to allow to customize neutron ml2 drivers. This Epic will take care of certification guide / procedure only. See the linked Epic for the actual implementation.
