Add ClusterSelector to Ingress Controller

This pull request adds ClusterSelector to the Federated Ingress Controller ref: design #29887 
This back ports the same functionality from the sync controller (merged pull #40234) in order to make this feature available across all Controllers for the 1.7 release.

**Release note**:
```
The annotation `federation.alpha.kubernetes.io/cluster-selector` can be used with Ingress objects to target federated clusters by label.
