Stop propagating proxy env to router pod

[enxebre]

This was merged in #930. In hypershift the operator pod runs in a different cluster than the router pod, and so they might have different proxy configs. We set ootb proxy settings for the operator to go through konnectivity. I think because this got introduced in this PR https://github.com/openshift/cluster-ingress-operator/pull/930/files\#diff-03760f03eeac1174e38e1ec5fecadcab4cb38d05e00509f201d7ae64dc1c7c36R1044-R1048 now those proxy settings are being propagated down to the router pod and so breaking hypershift.

See an example on how we diferenciate in the cluster network operator https://github.com/openshift/hypershift/blob/f03113aec2545aa08f85ab0e2fa0a790f709aacb/control-plane-operator/controllers/hostedcontrolplane/cno/clusternetworkoperator.go\#L341-L347
