cilium: 4 sig-network tests fail (sonobuoy)

Created by: garloff

Testing a capo cluster with k8s-1.21.9, I consistently get 4 failed tests: Failed tests:

[sig-network] Services should have session affinity timeout work for service with type clusterIP [LinuxOnly] [Conformance]
[sig-network] Services should have session affinity work for service with type clusterIP [LinuxOnly] [Conformance]
[sig-network] HostPort validates that there is no conflict between pods with same hostPort but different hostIP and protocol [LinuxOnly] [Conformance]
[sig-network] Services should be able to switch session affinity for service with type clusterIP [LinuxOnly] [Conformance]

To Do: Investigate:

• Are they dependent on k8s version?
• Or anything that we'd need to take care of in our capi/capo setup?
