Subject: [PATCH v2 1/3] perf test: Add metric value validation test
Add metric value validation test to check if metric values are with in
correct value ranges. There are three types of tests included: 1)
positive-value test checks if all the metrics collected are non-negative;
2) single-value test checks if the list of metrics have values in given
value ranges; 3) relationship test checks if multiple metrics follow a
given relationship, e.g. memory_bandwidth_read + memory_bandwidth_write =
memory_bandwidth_total.
