Adding option to set the federation api server port if nodeport is set
**What this PR does / why we need it**: Kubefed will deploy the respected services and then it will do a health check. Prior to this patch if the user selects the nodeport a random port is opened. In environments where firewalls are in place this random port selection will cause the health check to fail. With this patch we enable users to designate a specific port, after for example opening it on their firewall.

Add NodeInternalIP as a fallback to federation api-server nodeport service
Previously NodeLegacyHostIP was used as a fallback (see #41243) but in 1.7 it was removed (#44830)
Now clusters where nodes have not set ExternalIP can not be used by kubefed to setup federation.
cc @shashidharatd
```release-note
kubefed will now configure NodeInternalIP as the federation API server endpoint when NodeExternalIP is unavailable for federation API servers exposed as NodePort services

[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] Make --dns-provider mandatory for kubefed
Targets #40757
I thought about adding a test for this but I decided it wasn't worth it. There's too much setup involved in being able to run ``Complete`` for such a simple change.
**Release note**:
```release-note
The --dns-provider argument of 'kubefed init' is now mandatory and does not default to `google-clouddns`. To initialize a Federation control plane with Google Cloud DNS, use the following invocation: 'kubefed init --dns-provider=google-clouddns'
```

[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.
```
