Return clusterErr rather than err
The updateClusterIngressUIDToMasters() should return clusterErr, not err.
If the 'err' of 'masterCluster, masterUID, err := ic.getMasterCluster()' is nil and the 'clusterErr' of 'clusterObj, clusterErr := api.Scheme.DeepCopy(cluster)' is not nil, updateClusterIngressUIDToMasters() will return ("", nil).
And do not log fallbackUID when fallbackUID is nil.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet

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

deduplicate endpoints before DNS registration
**What this PR does / why we need it**: Multizone clusters will return duplicated endpoints to the federation controller manager. The FCM will then attempt to create an A record with duplicate entries, which will fail. As a result, federated services on multi-AZ clusters don't work right now. This PR deduplicates the endpoint IPs before attempting the DNS record registration.
**Which issue this PR fixes**: fixes#35997
**Special notes for your reviewer**:
I believe there is a lot of refactoring required with multizone federated clusters, most notably with regard to AWS and optimising for ALIAS records rather than A, but this PR will at least allow basic functionality to work.
```release-note NONE
```
This is intended to make it easier to define the interaction between cluster selection and scheduling preferences in the sync controller when used for workload types.

[Federation] Segregate DNS related code to separate controller
**What this PR does / why we need it**:
This is the continuation of service controller re-factor work as outlined in #41253
This PR segregates DNS related code from service controller to another controller `service-dns controller` which manages the DNS records on the configured DNS provider.
`service-dns controller` monitors the federated services for the ingress annotations and create/update/delete DNS records accordingly.
`service-dns controller` can be optionally disabled and DNS record management could be done by third party components by monitoring the ingress annotations on federated services. (This would enable something like federation middleware for CoreDNS where federation api server could be used as a backend to CoreDNS eliminating the need for etcd storage.)
**Special notes for your reviewer**:
**Release note**:
```
Federation: A new controller for managing DNS records is introduced which can be optionally disabled to enable third party components to manage DNS records for federated services.
