Fix namespace support in kubectl aging plugin

This commit adds use of the conveyed namespace information to the
plugin example.

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.
