extracted elasticsearch-logging service name as environment variable
**What this PR does / why we need it**:

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.

In error case, the condition “gotErr != test.err && gotPath !=
test.expectedPath” never fulfill because in this case both gotPath and
test.expectedPath always an empty string. So the err “err: `field "what?"
does not exist`” doesn’t get tasted. For example, if you change the value of
“err” to anything, the test still will pass. Also, since gotPath is empty
string in case of err, in the output error we probably don’t want to display
path.

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.
I guess we're not having this problem for config-test.sh where we're mostly creating new network.
