At the moments we have a couple of workgen workloads to observe cache behavior, like bench/workgen/runner/cache_workload_*.py
More workloads will be added. These workloads will be useful to assess the impact of the changes to cache and eviction subsystems.
The output files workload.stat, latency.stat, cache_eviction.stat contains the metrics to assess the impact of the code changes.

The scope of this ticket is to build a tool to generate graphs / charts from the data points from the output files of these workloads.
