re-enable nodeipam in kube-controller-manager
**What this PR does / why we need it**:
Re-enables nodeipam controller for external clouds. Also does a small refactor so that we don't need to pass in `allocateNodeCidr` into the controller.
In v1.10 we made a change (9187b343e1 (diff-f11913dc67d80d36b3d06a93f61c49cf) in https://github.com/kubernetes/kubernetes/pull/57492) where nodeipam would be disabled for any cluster that sets `--cloud-provider=external`. The original intention behind this was that the nodeipam controller is cloud specific for some clouds (only GCE at the moment) so it should be moved to the CCM (cloud controller manager). After some discussions with wg-cloud-provider it makes sense to re-enable nodeipam controller in KCM and have GCE CCM enable its own cloud-specific IPAM controller as part of [Initialize()](https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/cloud.go#L33-L35). This would allow for GCE to run nodeipam in both KCM (by setting --cloud-provider=gce and --allocate-node-cidr) and in the CCM (once implemented in `Initialize()`) without disabling nodeipam in the KCM for all external clouds and avoids having to implement nodeipam in CCM.

explicit kubelet config key in Node.Spec.ConfigSource.ConfigMap
This makes the Kubelet config key in the ConfigMap an explicit part of
the API, so we can stop using magic key names.
As part of this change, we are retiring ConfigMapRef for ConfigMap.
```release-note
You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file.

remove incorrect static restmapper from type registry
A RESTMapping can only be determined by inspecting a server since discovery is the authoritative source of mapping decisions. This removes a deceptive method from the type registry and makes the old logic available for existing tests in a separate, clearly labeled package.

divide statically known typer from dynamically derived restmapper
The CLI factory conflated a statically known typer and a dynamically derived restmapper. This produced confusion and unnecessary indirection. This pull separates dynamically known from statically known.
A future pull will continue the separation of in the builder to indicate the points of variability for clients, which should logically be limited to a negotiated serializer for decoding and an object typer.
