remove pkg/feature dependency from genericapiserver.
@sttts I think you just forgot this when you were snipping the rest of the link. If I understood the previous pull correctly, this ought to ensure proper registration of the bits we need, right?

move the discovery and dynamic clients
Moved the dynamic client, discovery client, testing/core, and testing/cache to `client-go`. Dependencies on api groups we don't have generated clients for have dropped out, so federation, kubeadm, and imagepolicy.

Wait for the self-hosted control plane during kubeadm init.
**What this PR does / why we need it**:
Currently we are completing kubeadm init while the scheduler and
controller manager are likely still not yet up. In some cases if they
will fail, they won't ever come up.
Instead wait until each pod enters running state before exiting kubeadm.
**Release note**:
```release-note
NONE

update kubectl approvers
All the other owners files have names (not groups). Updated for individual users for approvers so `/approve` works.

move client/cache and client/discovery to client-go
mechanical changes to move those packages. Had to create a `k8s.io/kubernetes/pkg/client/tests` package for tests that were blacklisted from client-go. We can rewrite these tests later and move them, but for now they'll still run at least.

kubeadm: Fix up the apiserver kubelet client cert
**What this PR does / why we need it**:
I didn't notice that the apiserver serving cert was _only_ a server cert, not both a server and client cert in https://github.com/kubernetes/kubernetes/pull/40292.
This PR fixes that misconception and generates a dedicated client cert for apiserver -> kubelet communication and harmonizes the `ca.crt` path to `/etc/kubernetes/pki/ca.crt` on both master and node.

make client-go tools/auth and tools/clientcmd authoritative
These moved easily. Pure mechanical. I'll have a couple snip pulls for some of the more complicated packages. `pkg/util/homedir` was a transitive that moved with. It was only used in `kubectl` and you'd need it to be consistent with `clientcmd` loading order.

kubeadm: Secure apiserver -> kubelet communication and set storage backend to etcd3
**What this PR does / why we need it**:
Switch storage backend to etcd3
Writes ca.crt down to disk so we can set `--client-ca-file=/etc/kubernetes/ca.crt` for the kubelet.
Adds --kubelet-client-{certificate,key} to the apiserver args and make it allowed to access the kubelets
In some cases the `path` dependency is switched to `filepath`
