[FeatureRequest] Tolerations and NodeSelector

I would like to propose the addition of support for Tolerations and NodeSelector in the Nginx Ingress Controller. This feature is essential for users like myself who need to deploy resources on dedicated NodePools. By allowing Tolerations and NodeSelectors to be configured, we can ensure that the Nginx Ingress Controller can effectively manage traffic on specific nodes that meet our resource and performance requirements.

```
tolerations:
- key: infra
operator: Equal
value: "true"
effect: NoSchedule
nodeSelector:
type: infra
```

The issue names no files, tests, or entry points. Start by locating the Nginx Ingress Controller deployment configuration and related tests; done means Tolerations and NodeSelector can be configured for dedicated node pools and the behavior is covered by tests.
