update script to work with 0.5.4 aws-k8s-tester

The names of environment variables accepted by aws-k8s-tester changed
when the managed node group functionality was introduced. This commit
updates the integration testing scripts to call aws-k8s-tester (v.0.5.4
which is the release needed with the fix for aws/aws-k8s-tester#70) with
these updated environment variables.

We decrease the number of parallel builds of the echo job from 100 to
3 and the number of completions for that job from 1000 to 30. This
decreases the setup time of the cluster by about 10 minutes.

Finally, I added in a short-circuit to prevent double-deprovisioning of
the cluster if, say, a stacktrace occurred when running the
aws-k8s-tester tool.
