1. Proposed title of this feature request

Ability to configure nodeSelector/tolerations in GatewayClass 

2. What is the nature and description of the request?

Currently there are no abilities to configure nodeSelector/tolerations in GatewayClass

As a result pods deployed in openshift-ingress namespace cannot be moved on infra nodes such:

• istiod
• kube-auth-proxy
• istio-proxy

3. Why does the customer need this? (List the business requirements here)

Many AI customers have only tainted worker GPU nodes to prevent the scheduling of non AI business related workload in those expensive nodes. They don't have any other worker node types. They expect the OCP platform component to run in infra node in order to:

• save subscriptions from pure platform related workload
• save space in their expensives GPU nodes 

4. List any affected packages or components.
