Add toleration to fluentd daemonset to make it run on master
Because of https://github.com/kubernetes/kubernetes/pull/41172 fluentd pods stopped being allocated on master node.
This PR introduces toleration for master taint for fluentd.

Unfortunately, we don't have e2e tests to ensure that master logs are being ingested. This problem is a great signal to work on https://github.com/kubernetes/kubernetes/issues/41411

Fix https://github.com/kubernetes/kubernetes/issues/41415
Fluentd for Stackdriver requires external urls (e.g. `logging.googleapis.com`) to be available in order to work. If fluentd runs on master, it cannot access the service endpoint of cluster DNS. This change makes fluentd use default dns to fix this problem.

Remove alpha provisioning
This is the first part of https://github.com/kubernetes/features/issues/36
@kubernetes/sig-storage-misc
**Release note**:
```release-note
Alpha version of dynamic volume provisioning is removed in this release. Annotation
"volume.alpha.kubernetes.io/storage-class" does not have any special meaning. A default storage class
and DefaultStorageClass admission plugin can be used to preserve similar behavior of Kubernetes cluster,
see https://kubernetes.io/docs/user-guide/persistent-volumes/#class-1 for details.

Always detach volumes in operator executor
**What this PR does / why we need it**:
Instead of marking a volume as detached immediately in Kubelet's
reconciler, delegate the marking asynchronously to the operator
executor. This is necessary to prevent race conditions with other
operations mutating the same volume state.
An example of one such problem:
1. pod is created, volume is added to desired state of the world
2. reconciler process starts
3. reconciler starts MountVolume, which is kicked off asynchronously via
operation_executor.go
4. MountVolume mounts the volume, but hasn't yet marked it as mounted
5. pod is deleted, volume is removed from desired state of the world
6. reconciler reaches detach volume section, detects volume is no longer in desired state of world,
removes it from volumes in use
7. MountVolume tries to mark mount, throws an error because
volume is no longer in actual state of world list. After this, kubelet isn't aware of the mount
so doesn't try to unmount again.
8. controller-manager tries to detach the volume, this fails because it
is still mounted to the OS.
9. EBS gets stuck indefinitely in busy state trying to detach.

Add field to control service account token automounting
Fixes https://github.com/kubernetes/kubernetes/issues/16779
* adds an `automountServiceAccountToken *bool` field to `ServiceAccount` and `PodSpec`
* if set in both the service account and pod, the pod wins
* if unset in both the service account and pod, we automount for backwards compatibility
```release-note
An `automountServiceAccountToken *bool` field was added to ServiceAccount and PodSpec objects. If set to `false` on a pod spec, no service account token is automounted in the pod. If set to `false` on a service account, no service account token is automounted for that service account unless explicitly overridden in the pod spec.

e2e test for storage class diskformat verification for vsphere cloud provider
**What this PR does / why we need it**:
This PR adds a new e2e test for vsphere cloud provider.
Test is to verify diskformat specified in storage-class is being honored while volume creation.
Steps:
1. Create StorageClass with diskformat set to valid type (supported options are `eagerzeroedthick`, `zeroedthick` and `thin`)
2. Create PVC which uses the StorageClass created in step 1.
3. Wait for PV to be provisioned.
4. Wait for PVC's status to become Bound
5. Create POD using PVC on specific node.
6. Wait for Disk to be attached to the node.
7. Get node VM's devices and find PV's Volume Disk.
8. Get Backing Info of the Volume Disk and obtain Property of `VirtualDiskFlatVer2BackingInfo` - `EagerlyScrub` and `ThinProvisioned`
9. Based on the value of `EagerlyScrub` and `ThinProvisioned`, verify if diskformat is correct.
10. Delete POD and Wait for Volume Disk to be detached from the Node.
11. Delete PVC, PV and Storage Class

Stop controller when the stop channel is closed (when queue is empty and Pop is hanging)
Fixes: #28158
When a ``Pop`` function is invoked over empty queue, the control loop inside the functions is stacked indefinitely. In order to break the loop, introduce logic that waits for a signal to exit the loop.
Intention of the PR is not to handle situation where manipulation operations are invoked over closed queue. Intention is to break the indefinite loop.

Change node e2e cri-validation configs
Copy the configs to a new directory to test non-cri implementation. We can
remove the original directory after the dependent PRs are merged.
make sure that one of the two arguments must be non-nil: runningPod, status ,just like the function note says
and judge the return value in syncPod() function before setting podKilled

openstack-heat: do not daemonize salt-minion
_openstack-heat_ does currently not setup a _salt-master_, so it is not necessary to daemonize it.
**What this PR does / why we need it**:
as stated in #40721:
> The _openstack-heat_ provider only installs _salt-minions_, no _salt-master_. The configuration does not take this into account which causes the following issues:
>
> - the _salt minion_ is not able to DNS resolve `salt` (see fist part of error log below)
> - the _salt-minion_ is daemonized and fails finding the master (second part of error log below). From my understanding is not required when there is no salt-master, as the setup uses `salt-call`
> anyway (see [gce provider](https://github.com/kubernetes/kubernetes/blob/master/cluster/gce/configure-vm.sh#L328-L339) as reference).
>
> ```
> Jan 31 03:00:04 kube-stack-master salt-minion[9795]: [ERROR ] DNS lookup of 'salt' failed.

Change the etcd rollback tool to do rollback to 2.2.1 version.
I did some tests of it and for my 3-node cluster with 1 deployment it worked fine.
But before merging this, we should probably do way more testing (we should rerun tests that @mml was doing for the previous script).
