In hypershift power agent platform, the default ingresscontroller has a node selector to bind all of the pods to just one node. It conflicts with its topology in infra HA mode.

Note:
if we delete the ingresscontroller/default in openshift-ingress-operator manually. It will be recreated again without any nodeselector
So after it is created again. The pod could be scheduled successfully without that invalid nodeselector.
