Add test image name to the OS image field of the perf metrics

I'd like to add the resource usage benchmarks for COS m60 (docker 1.13.1) but don't want to remove the existing m59 (docker 1.11.2) [ones](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/jenkins/benchmark/benchmark-config.yaml#L51-L71), in order to compare the results between the two docker versions.

The `image` reported in the metrics is from `Node.Status.NodeInfo.OSImage`, which is always "Container-Optimized OS from Google" (from `/etc/os-releases`) for COS. So there's no way to differentiate two milestones in the metrics.

This PR attaches the [image name](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/jenkins/benchmark/benchmark-config.yaml#L52) to the `image` field of the metrics. So it will become "Container-Optimized OS from Google (cos-stable-59-9460-64-0)".

See the results of the test run:

LocalPV e2e test with two pods writing/reading to a shared file on one PVC

**What this PR does / why we need it**:

This PR adds an e2e test where one pod writes to a localPV and another reads from it. This e2e test is for the PersistentLocalVolumes alpha feature.

**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubernetes/issues/48832

**Special notes for your reviewer**:

You need to setup the PersistentLocalVolumes feature-gate and NODE_LOCAL_SSDS environment variable.

For example:

```
KUBE_FEATURE_GATES="PersistentLocalVolumes=true" NODE_LOCAL_SSDS=1 go run hack/e2e.go -- -v --up

go run hack/e2e.go -- -v --test --test_args="--ginkgo.focus=\[Feature:LocalPersistentVolumes\]"

Fix subPath existence check to not follow symlink

**What this PR does / why we need it**:
Volume mounting logic introduced in #43775 and #45623 checks
for subPath existence before attempting to create a directory,
should subPath not be present.

This breaks if subPath is a dangling symlink, os.Stat returns
"do not exist" status, yet `os.MkdirAll` can't create directory
as symlink is present at the given path.

This patch makes existence check to use os.Lstat which works for
normal files/directories as well as doesn't not attempt to follow
symlink, therefore it's "do not exist" status is more reliable when
making a decision whether to create directory or not.

subPath symlinks can be dangling in situations where kubelet is
running in a container itself with access to docker socket, such
as CoreOS's kubelet-wrapper script

**Release note**:
```release-note
Fix pods failing to start when subPath is a dangling symlink from kubelet point of view, which can happen if it is running inside a container
```

StatefulSet upgrade test - replicated database (mysql)

**What this PR does / why we need it**:
Adds a new upgrade test. The test creates a statefulset with a replicated mysql database. It populates the database and then continually polls the data while performing an upgrade. 

Ultimately, this PR increases confidence of reliability during upgrades. It helps show that StatefulSets and Pod Disruption Budgets are doing what they're supposed to.  Code to pay attention to this was added for #38336.

Also vendors in a golang mysql client driver, for use in the test.

kubeadm: Start to remove old envparams

**What this PR does / why we need it**:

Historically, the envparams feature was used as a way to easily debug `kubeadm` while developing it in the v1.3-v1.4 timeframe. Since then some parameters have been hanging around and not being moved into the API as they should have.

Note: This is a temporary step; moving things into the API. Still, the API is gonna change, this is not the end state. But this is better than keeping the envparams.

I'm gonna deal with `KubernetesDir` in the next PR.

vSphere for cloud-controller-manager

**What this PR does / why we need it**:
This is to implement the `NodeAddressesByProviderID` and `InstanceTypeByProviderID` methods for cloud-controller-manager for vSphere cloud provider.

Currently vSphere cloud provider only supports VMs in the same folder.
Thus `NodeAddressesByProviderID` is similar to `NodeAddresses` with a simple ProviderID to NodeName translation.

`InstanceTypeByProviderID`  returns nil as same as `InstanceType`.
