In order to use -n, the value needs either be quoted or [[ .. ]] block
has to be used. Fix the comparisons that way.
To verify, consider this (analogous) script:
#!/bin/bash
subnetwork_url=""
if [ -n ${subnetwork_url} ]; then
echo "foo"
fi
if [[ -n ${subnetwork_url} ]]; then
echo "bar"
fi
Here "foo" is echoed by the script, even though the variable
subnetwork_url has a zero-length value.
In shell scripts inside [[ .. ]] blocks, ">" is a string comparison operator.
The "attempt" number comparison works (most likely by accident) because the max
number of attempts is below 10. Change to -gt operator.

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.

Remove mapping to /host/lib from fluentd-gcp container.
**What this PR does / why we need it**:
This mapping is no longer needed since fluentd-gcp v2.0.16, in which it started using a container image based on Debian Stretch, in which the systemd libraries already include support for all the supported
compression algorithms.
The `/run.sh` in the image no longer accesses `/host/lib` anyways, so let's stop mapping it here.

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.
```
