Zombienet k8 Cluster for sTPS measurements

[bernardoaraujor]

We are attempting to use Zombienet as the main network orchestration tool for collecting sTPS measurements. The idea is to use a Kubernetes cluster that isolates one node per bare-metal machine. That means we need a new Kubernetes Cluster in Parity's infrastructure.

The machines should be as close as possible to what is currently used for the Polkadot Validator infrastructure, and we need to document them in the methodology docs.

We are starting with simple setups, where 10 machines should be enough. But as the setups scale up, that number should also increase in the near future.
