Set default vmtype to standard if not set
**What this PR does / why we need it**:
When using IMDS, kubelet reports Failed to extract vmssVMName even when vmtype is not set:

kubeadm 710 Switch to a dedicated CA for kubeadm etcd identities
**What this PR does / why we need it**:
On `kubeadm init`/`kubeadm upgrade`, this PR generates an etcd specific CA for signing the following certs:
- etcd serving cert
- etcd peer cert
- apiserver etcd client cert
These certs were previously signed by the kubernetes CA.
The etcd static pod in `local.go` has also been updated to only mount the `/etcd` subdir of `cfg.CertificatesDir`.
New phase command:
```
kubeadm alpha phase certs etcd-ca
```
See the linked issue for details on why this change is an important security feature.
**Which issue(s) this PR fixes**
Fixes https://github.com/kubernetes/kubeadm/issues/710
**Special notes for your reviewer**:
#### on the master
this should still fail:
```bash
curl localhost:2379/v2/keys # no output
curl --cacert /etc/kubernetes/pki/etcd/ca.crt https://localhost:2379/v2/keys # handshake error
```
this should now fail: (previously would succeed)
```
cd /etc/kubernetes/pki
curl --cacert etcd/ca.crt --cert apiserver-kubelet-client.crt --key apiserver-kubelet-client.key https://localhost:2379/v2/keys
# curl: (35) error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate
```
this should still succeed:
```

curl --cacert etcd/ca.crt --cert apiserver-etcd-client.crt --key apiserver-etcd-client.key https://localhost:2379/v2/keys
```
**Release note**:

On cluster provision or upgrade, kubeadm generates an etcd specific CA for all etcd related certificates.

dockershim: Return Labels as Info in ImageStatus.
c6ddc749e8 added an Info field to
ImageStatusResponse when Verbose is true. This makes the image's
Labels available in that field, rather than unconditionally returning
an empty map.
**What this PR does / why we need it**:
This PR exposes an image's `Labels` through the CRI. In particular, I want this so I can write an `ImageService` wrapper that delegates all operations to a real `ImageService` but also, when the right `Labels`, ensures any needed [nix store](https://nixos.org/nix/) paths are present on the system when an image is pulled, enabling users to use nix for package distribution while still using containers for isolation and kubernetes for orchestration. In general, though, this should be useful for anything that wants to know about an image's `Labels`
**Special notes for your reviewer**:
I'd prefer to put this change into the `Image` protobuf type instead of putting it into `Info` (gated by `Verbose` or not, available in other requests like `ListImages` or not), but that would be a change to the protocol and it seems `Info` was introduced exactly for this purpose. If it's acceptable to put this into `Image`, I'll rework this.
If this change is acceptable, I will also do the work for `cri-o`, `rktlet`, `frakti`, and `cri-containerd` where applicable.
I have started the process for my employer to sign on to the CLA. I don't have reason to expect it to take long, but because there is more work to do if this change is desired I'd prefer if we can start review before that is completed.
**Release note**:
```release-note
dockershim now makes an Image's Labels available in the Info field of ImageStatusResponse

Changing Flexvolume plugin directory on COS in GCE to a durable directory
**What this PR does / why we need it**: The original `/etc/srv/...` directory is in an overlayfs over a path in /tmp, so Flexvolume drivers are erased across node restarts for any reason. Changing it to non-tmpfs location.
Also removing redundant Flexvolume path injection in `config-test.sh` because it's already in `cluster/common.sh`.

Increase failureThresholds for failing HTTP liveness test
**What this PR does / why we need it**:
Removes test from e2e which relies on HTTP liveness as a measure to tell if the container is good or bad. While this is not a bad idea, we cannot rely on this test as HTTP liveness relies on network/infrastructure etc on which sometimes we have no control over. While increasing the timeout may be an option it may not be ideal for all cloud providers/type of hardware etc.
