remove validation dependency on version negotiation
Things that just need a REST client or a bit of discovery information should not attempt to perform negotiation. Doing so just limits the genericness of the client.
@kubernetes/sig-cli
@fabianofranz this blocks the kubernetes-discovery work.

make invocation ReadDockerConfigFile can handle .dockerconfigjson file
**What this PR does / why we need it**:
When **.docker/config.json** is used to authenticate docker registry, the data key **.dockerconfigjson** should be used if we want to save this kind of docker auth data into a secret. So this PR is mainly to make invocation `ReadDockerConfigFile `have ability to read **.dockerconfigjson** file.

Fix scheduler_perf test so that QPS is non-zero even if there is a scheduling "cold start"
@gmarek ... is something like this more realistic as an expectation ? That is, wait till scheduling starts, then wait 1 second before any polling attempts.... i.e.
- gaurantee uniform sleep before measure, by doing it first rather then last
- print the initial status so that its easier to debug in case of issues

Add a cloudprovider validator flag to kubeadm and update the DNS spec
Broken out from: https://github.com/kubernetes/kubernetes/pull/37568
This PR creates a flag for `cloud-provider` that validates the value before `RunInit()` is run, which makes it now act as a "real" flag
Then it removes the `k8s.io/kubernetes/pkg/cloudprovider` dependency, which makes the binary ~40MB smaller! That's _really_ worth it!
In the second commit, the DNS addon is updated to the latest version: https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/dns/skydns-rc.yaml.base

Only configure basic auth on gci if KUBE_USER and KUBE_PASSWORD are specified.
This should not change the existing flow when KUBE_USER/KUBE_PASSWORD are specified.
It makes not specifying those a valid option that means "don't turn on basic auth".
I only did it for cluster/gce/gci for now, but others should be somewhat similar.

fix permissions when using fsGroup
Currently, when an fsGroup is specified, the permissions of the defaultMode are not respected and all files created by the atomic writer have mode 777. This is because in `SetVolumeOwnership()` the `filepath.Walk` includes the symlinks created by the atomic writer. The symlinks have mode 777 when read from `info.Mode()`. However, when the are chmod'ed later, the chmod applies to the file the symlink points to, not the symlink itself, resulting in the wrong mode for the underlying file.
This PR skips chmod/chown for symlinks in the walk since those operations are carried out on the underlying file which will be included elsewhere in the walk.

Re-use tested ratelimiter
The ratelimiter introduced in #35583 is not working correctly when called from multiple threads
This reverts to the tested ratelimiter we were previously using to unblock 1.5 (automated revert wasn't possible)
Ref #38273
reproducing test case:
```
func TestMultiThreadedBlocking(t *testing.T) {
done := make(chan bool)
// 100 QPS, burst of 100
b := NewBucketWithRate(100, 100)
go func() {
defer close(done)
fmt.Println(time.Now(), "Waiting for 1000 (should block for ~9-10 seconds)")
b.Wait(1000)
fmt.Println(time.Now(), "Got 1000")
}()
// give the request for 1000 plenty of time to take the tokens
time.Sleep(2 * time.Second)
fmt.Println(time.Now(), "Waiting for 1 (should wait until 1000 block is refilled)")
b.Wait(1)
fmt.Println(time.Now(), "Got 1 (should happen right after the wait for 1000 completes)")
<-done
}

I think we should not allow people set duplicate tokens in token file or set duplicate usernames in password file. because the default action overwriting the old data may let people misunderstand.
