* Fix reference CNI plugins * The plugins were split out of the upstream cni repo around version 0.6.0 * Fix RBAC and DNS tests * Fix broken apiVersion fields * Change plugin linking to look in ${package}/bin rather than ${package.plugins} * Initial work towards a working e2e test * Test still fails, but at least the expression evaluates now Continues @srhb's work in #37199 Fixes #37199
