Merge pull request #43137 from shashidharatd/federation-domain

Automatic merge from submit-queue [Federation] Remove FEDERATIONS_DOMAIN_MAP references Remove all references to FEDERATIONS_DOMAIN_MAP as this method is no longer is used and is replaced by adding federation domain map to kube-dns configmap. cc @madhusudancs @kubernetes/sig-federation-pr-reviews **Release note**: ``` [Federation] Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action. ```
