Related to: kubernetes/kubernetes#135026

Bumps ginkgo parallelism of the hpa-cpu job to 10. To accomodate this, each worker node will be the e2-highcpu-8 instances type. These have 8 CPU and 8 GiB of memory each: https://gcloud-compute.com/e2-highcpu-8.html.

This is limit testing, but I think the infrastructure should be able to handle 10 concurrent tests with 24 CPU total in the gce cluster. At least according to my crude math in the original issue.

If we tried parallelism of 6, I believe our 4 CPU worker nodes would make the tests flake.
