Add AUTOSCALER_ENV_VARS to kube-env to hotfix cluster autoscaler
This provides a temporary way for the cluster autoscaler to get at
values that were removed from kube-env in #60020. Ideally this
information will eventually be available via e.g. the Cluster API,
because kube-env is an internal interface that carries no stability
guarantees.
This is the first half of the fix; the other half is that cluster autoscaler
needs to be modified to read from AUTOSCALER_ENV_VARS, if it is
available.
Since cluster autoscaler was also reading KUBELET_TEST_ARGS for the
kube-reserved flag, and we don't want to resurrect KUBELET_TEST_ARGS in kube-env,
we opted to create AUTOSCALER_ENV_VARS instead of just adding back
the old env vars. This also makes it clear that we have an ugly dependency
on kube-env.

"create --mode" becomes "create --subnet-mode", and switch-mode has been
folded into "update".
Create --mode was deprecated in October and will be removed in the next
gcloud release. It is already failing in staging tests.

Bump to etcd 3.1.12 to pick up critical fix
etcd [3.1.12](https://github.com/coreos/etcd/releases/tag/v3.1.12) (as well as 3.2.17 and 3.3.2) was released yesterday to fix a bug critical to kubernetes:
Fix [mvcc "unsynced" watcher restore operation](https://github.com/coreos/etcd/pull/9297).
- "unsynced" watcher is watcher that needs to be in sync with events that have happened.
- That is, "unsynced" watcher is the slow watcher that was requested on old revision.
- "unsynced" watcher restore operation was not correctly populating its underlying watcher group.
- Which possibly causes [missing events from "unsynced" watchers](https://github.com/coreos/etcd/issues/9086).
This will be backported to 1.9 as well.
Release note:
```release-note
Upgrade the default etcd server version to 3.1.12 to pick up critical etcd "mvcc "unsynced" watcher restore operation" fix.
```

Pass in etcd TLS credentials during migrate and rollback
For HA etcd clusters, the `etcd-creds` settings, specifically the `--peer-*` TLS flags that may be included, must be passed in to `start-stop-etcd.sh` in order for the etcd server mode started during migrate and rollback steps to be able to communicate between peers.

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`.

Move kubelet flag generation from the node to the client
Pass the kubelet flags through a new variable in kube-env (KUBELET_ARGS).
Remove vars from kube-env that were only used for kubelet flags.
This will make it simpler to gradually migrate to dynamic kubelet
config, because we can gradually replace flags with config file
options in a single place without worrying about the plumbing to
move variables from the client onto the node.
