Description Abu Kashem 2020-10-08 13:30:16 UTC 
+++ This bug was initially created as a clone of Bug #1886442 +++

add p&f configuration to protect traffic from oauth server. 

The traffic from oauth server originates with the following SA:

    subjects:
    - kind: ServiceAccount
      serviceAccount:
        name: oauth-openshift
        namespace: openshift-authentication


assign the traffic from oauth to "workload-high" priority level.

After the change is made, we expect oauth traffic to be assigned to workload-high by p&f.
