CHG0076999 CITZ MCS SILVER - Migrate to OVN Container Network Interface

Scheduled
The current Container Network Interface (CNI) called OpenShift SDN is deprecated and not available in the next version of OpenShift. We need to move to OVNKubernetes CNI to unlock the upgrade path to OpenShift 4.18.
The upgrade requires a rolling restart of all nodes in the cluster twice. API nodes and Infra nodes are highly available and will fail over services as needed.
As the node drains are managed by OpenShift operator automation, Platform Ops has no way to control the speed of drains.
We may continue to see slow or delayed storage operations like mounting PVCs to pods. Pods drained from one node onto another node may see up to 45 min delay until it starts. The best solution is to have multiple replicas so that a single pod failing to start does not cause application downtime.
