Tooling

The tooling playbook is workloads/tooling.yml and will configure pbench tooling on master, infra, and two worker nodes. Pbench tooling will permit the collection of pbench tools over a test duration. The default tools are disk, iostat, mpstat, oc, perf and pidstat. More information regarding pbench can be found at https://github.com/distributed-system-analysis/pbench.
