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).

local-up-cluster: fix instructions for set-credentials
After launching the services, local-up-cluster.sh tells the
user how to configure kubectl to access it. The instructions
for 'set-credentials' enable plain password auth, but the
services are configured to mandate client certificate auth.
As a result it is not possible to access the cluster with
the instructions printed.
The use of client certs by default was added in

update negotiation to reflect current kubectl state
Very few things actually require negotiation, but the client-cache attempts it all the time. If you've explicitly requested one, you still fail. If you haven't requested one and the server doesn't have one, you still get the client behavior. After this, if you haven't requested one and the client and server don't have one, you simply get an empty you can interpret how you choose.
@lavalamp without this, you're unable to use `kubectl` against arbitrary servers.

Switch kubectl version and api-versions to create a discovery client …
…directly.
The clientset will throw an error for aggregated apiservers because the
clientset looks for specific versions of apis that are compiled into
the client. These will be missing from aggregated apiservers.
The discoveryclient is fully dynamic and does not rely on compiled
in apiversions.

switch admission serialized config to an apiserver type
Switches the kube admission config from componentconfig to the new `apiserver.k8s.io` group so that all API servers can use the shared configuration. This switch external serialization, but it does not move the code that reads the config. I'd like to do that as a follow-on.

Refactored kubemark code into provider-specific and provider-independent parts [Part-2]
Applying part of the changes of PR https://github.com/kubernetes/kubernetes/pull/39033 (which refactored kubemark code completely). The changes included in this PR are:
- Added test/kubemark/skeleton/util.sh which defines a well-commented interface that any cloud-provider should implement to run kubemark.
This includes functions like creating the master machine instance along with its resources, remotely executing a given command on the master (like ssh), scp, deleting the master instance and its resources.
All these functions have to be over-ridden by each cloud provider inside the file /test/kubemark/$CLOUD_PROVIDER/util.sh
- Implemented the above mentioned interface for gce in /test/kubemark/$CLOUD_PROVIDER/util.sh
- Made start- and stop- kubemark scripts (almost) provider independent by making them source the interface based on cloud provider.

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.

[Federation][kubefed] Add option to expose federation apiserver on nodeport service
**What this PR does / why we need it**:
This PR adds an option to kubefed to expose federation api server over nodeport. This can be useful to deploy federation in non-cloud environments. This PR is target to address #39271
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```
[Federation] kubefed init learned a new flag, `--api-server-service-type`, that allows service type to be specified for the federation API server.
[Federation] kubefed init also learned a new flag, `--api-server-advertise-address`, that allows specifying advertise address for federation API server in case the service type is NodePort.

Add SIG to test owners
**What this PR does / why we need it**:
This PR adds a `sig` column to the test owners file generation script.
A problem experienced with the current owners file is that since members are auto-assigned there are times where tests are assigned to non-active users who don't follow up to notifications to fix flakes. By assigning a SIG to each test we can hold a group we know is active responsible for taking care of flakes it's less likely that flakes will fall through the cracks.
**Special notes for your reviewer**:
* A companion PR will go into *kubernetes/contrib* adding support for mungers parsing this new column.
* Another PR in contrib will add labeling GitHub flake issues with the appropriate SIG
* Currently SIGs are not labeled, this will be added in another PR where SIG determinations can be discussed

PV E2E: provide each spec with a fresh nfs host
**What this PR does / why we need it**:
PersistentVolume e2e currently reuses an NFS host pod created at the start of the suite and accessed by each test. This is far less favorable than using a fresh volume per test. Additionally, this guards against the volume host pod or it's kubelet being disrupted, which has led to flakes.
