After today's SIG meeting, it was discussed how to proceed with these
types of test-cmd tests. They will live in kubeamd/test/cmd and will
provide a flag that will allow you to skip them (--kubeadm-cmd-skip) and
by default will fail if kubeadm binary is not present

refactor approver and signer interfaces to be consisten w.r.t. apiserver interaction
This makes it so that only the controller loop talks to the
API server directly. The signatures for Sign and Approve also
become more consistent, while allowing the Signer to report
conditions (which it wasn't able to do before).

apiserver command line options lead to config
Logically command line options lead to config, not the other way around. We're clean enough now we can actually do the inversion.
WIP because I have some test cycles to fix, but this is all the meat.

Promote SubjectAccessReview to v1
We have multiple features that depend on this API:
SubjectAccessReview
- [webhook authorization](https://kubernetes.io/docs/admin/authorization/#webhook-mode)
- [kubelet delegated authorization](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authorization)
- add-on API server delegated authorization
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating access
- A typo was discovered in the SubjectAccessReviewSpec Groups field name
This PR promotes the existing v1beta1 API to v1, with the only change being the typo fix to the groups field. (fixes https://github.com/kubernetes/kubernetes/issues/32709)
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

kubeadm: change os.Remove to os.RemoveAll
**What this PR does / why we need it**: This would not correctly clean out the tmp dir, since os.Remove doesn't recursively remove dirs, which could exist in the tmp dir.
Unit tests are a WIP from #34136

Replace hand-written informers with generated ones
Replace existing uses of hand-written informers with generated ones.
Follow-up commits will switch the use of one-off informers to shared
informers.
This is a precursor to #40097. That PR will switch one-off informers to shared informers for the majority of the code base (but not quite all of it...).
NOTE: this does create a second set of shared informers in the kube-controller-manager. This will be resolved back down to a single factory once #40097 is reviewed and merged.
There are a couple of places where I expanded the # of caches we wait for in the calls to `WaitForCacheSync` - please pay attention to those. I also added in a commented-out wait in the attach/detach controller. If @kubernetes/sig-storage-pr-reviews is ok with enabling the waiting, I'll do it (I'll just need to tweak an integration test slightly).

kubeadm: app/util/template.go has unit tests

Kubeadm discovery remove error passing
**What this PR does / why we need it**: In the app/discovery there is some confusion about the passing of error values created in the discovery/token, discovery/https/ and discovery/file pkgs. Since they always return `nil` , it was very confusing in discovery/flags.go why to propagate them up as if there was a chance for them to return a value other than `nil`. This change makes it much more clear what is being passed.
I noticed this as I was making a sweep through trying to add more unit tests and it was very confusing to read the code.

kubeadm: Remove the kubernetes.io/cluster-service label from the Deployment templates
**What this PR does / why we need it**:
As discussed on Slack, these labels have no function when not using the addon-manager, so it's best to remove them to avoid confusion.
