[Federation][kubefed]: Set apiserver to bind securely to 8443 instead of 443
On platforms like OpenShift that don't run containers as root by default, binding to ports < 1000 is not permitted. Having the apiserver bind to a high port means it can run with reduced privileges. The service will still expose the apiserver on 443, so this change shouldn't impact clients of the federation api.

[Federation] Create configmap for the cluster kube-dns when cluster joins and remove when it unjoins
This PR implements the functionality as needed in https://github.com/kubernetes/kubernetes/issues/38400
cc @kubernetes/sig-cluster-federation @nikhiljindal @madhusudancs
**Release note**:
```
kubefed join can now automatically create a configmap or add information to already existing one, storing this federation name vs zone name information in the joining cluster.
Further kubefed unjoin can remove this configmap or only this information from the configmap, if the unjoin cluster is registered with multiple federations.
The name of the configmap is kube-dns and the information in it is consumed by the in-cluster dns server.
