What this PR does / why we need it:
Align with CNAO.
Check if here the tests are passing.

pod can't be created failed to find plugin "calico" in path [/opt/cni/bin]
It seems we need to update calico according projectcalico/calico#6218
but not sure this is the problem

doesnt help

maybe worth to align more stuff which are different versus how cnao runs ovs cni, such as multus

[oshoval]

Note that if i tried to delete calico pods, sometimes one of them didnt manage to restart due to the same error as above
and i saw this

$ oc logs -n kube-system kube-apiserver-node01  | grep validated
E0927 14:28:25.716451       1 authentication.go:63] "Unable to authenticate the request" err="[invalid bearer token, service account token has been invalidated]"

which is also mentioned here projectcalico/calico#5684 (comment)

i think the right way is to try to align everything with CNAO, to see what is the moving part that does it
(updating calico didnt help)
worth to check if it is because we are using here multus thick
(need to check if cnao uses thin, calico test only with thin)

see #281
