Fix CRI fluentd config.

This should fix the cri-containerd stackdriver test failure:
```
Cluster level logging implemented by Stackdriver should ingest logs
```

I copied the pattern from a comment previously. However, it doesn't actually work properly. `\b` only matches word boundary, and seems to match the boundary of previous word in our case.

That's why we get the log with a leading space:
```
Nov 10 18:39:11.661: INFO: Unexpected error occurred: log entry ingested incorrectly, got --> <--I0101 00:00:00.000000       1 main.go:1] Text, want Text

Scale help

**What this PR does / why we need it**:
The `kubectl autoscale --help` says this:

```
# Auto scale a deployment "foo", with the number of pods between 2 and 10, target CPU utilization specified so a default autoscaling policy will be used:
  kubectl autoscale deployment foo --min=2 --max=10
```

This is incorrect. A default autoscaling policy will be used because *no* target CPU utilization has been specified.

Delete network by default in kube-down unless using default network

Since I'm seeing folks leak networks in one of our test project (k8s-scale-testing) if they're using kube-up to create/delete their network.
