Add a tool project to simulate pod churn.

[HughNhan]

Would like to add pod churn activity to simulate control plane workload to multibench.

@HughNhan do you think kube-burner should be used for this?

[HughNhan]

We could, but knowing that kube-burner orchestrates pod creation according to its methodology to measure podLatency (duration from creation to ready) in term of percentile. We could leverage kube-burner 's pod creation functionality with its nice control params i.e QPS, number of pods /node) etc, but Crucible will need to control (the start time and end time) this workload, and Crucible does not have a use for the metrics that kube-burner generates.
