Implement new package which primary goal is to collect and validate
performance metrics in managable way then dump them in JSON form for
further processing/storage.
Example usage:
container = PerfContainer()
container.insert_config_param("20.03.0000", ConfigParameter.CAS_VERSION)
container.insert_cache_metric(20000000, IOMetric.read_IOPS)
with open("perf.json", "w") as f:
json.dump(container.to_serializable_dict(), f)
