On my alderlake I currently see for the "perf metrics value validation" test:
```
Total Test Count: 142
Passed Test Count: 139
[
Metric Relationship Error: The collected value of metric ['tma_fetch_latency', 'tma_fetch_bandwidth', 'tma_frontend_bound']
is [31.137028] in workload(s): ['perf bench futex hash -r 2 -s']
but expected value range is [tma_frontend_bound, tma_frontend_bound]
Relationship rule description: 'Sum of the level 2 children should equal level 1 parent',
Metric Relationship Error: The collected value of metric ['tma_memory_bound', 'tma_core_bound', 'tma_backend_bound']
is [6.564442] in workload(s): ['perf bench futex hash -r 2 -s']
but expected value range is [tma_backend_bound, tma_backend_bound]
Relationship rule description: 'Sum of the level 2 children should equal level 1 parent',
Metric Relationship Error: The collected value of metric ['tma_light_operations', 'tma_heavy_operations', 'tma_retiring']
is [57.806179] in workload(s): ['perf bench futex hash -r 2 -s']
but expected value range is [tma_retiring, tma_retiring]
Relationship rule description: 'Sum of the level 2 children should equal level 1 parent']
Metric validation return with erros. Please check metrics reported with errors.
```
I suspect it is due to two metrics for different CPU types being
enabled. Add a -cputype option to avoid this. The test still fails with:
```
Total Test Count: 115
Passed Test Count: 114
[
Wrong Metric Value Error: The collected value of metric ['tma_l2_hit_latency']
is [117.947088] in workload(s): ['perf bench futex hash -r 2 -s']
but expected value range is [0, 100]]
Metric validation return with errors. Please check metrics reported with errors.
```
which is a reproducible genuine error and likely requires a metric fix.

The original test report was too complicated to read with information
that not really useful. This new update simplify the report which should
largely improve the readibility.

Avoid replicated logic by having a common library to set the PYTHON
environment variable.

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.
