Resource Monitoring metrics for Windows report utilization in the [0,100] range

[evgenyfedorov2]

Description

Metrics on Windows report values in the [0,100] range despite the documentation mentioning the [0,1] range: https://learn.microsoft.com/en-us/dotnet/core/diagnostics/built-in-metrics-diagnostics#metric-containercpulimitutilization

For example, if container CPU limit utilization is 60%, the metric reports the 60 value instead of 0.6.

Affected metrics:

1. dotnet.process.memory.virtual.utilization
2. process.cpu.utilization
3. container.memory.limit.utilization
4. container.cpu.limit.utilization

Reproduction Steps

Just use Resource Monitoring library on Windows and an exporter for the affected metrics, and you will see the incorrect values.

Expected behavior

Metrics on Windows report values in the [0,1] range as documented. For example, if container CPU limit utilization is 60%, the metric should report the 0.6 value

Actual behavior

Metrics on Windows report values in the [0,100] range. For example, if container CPU limit utilization is 60%, the metric reports the 60 value

Regression?

No, it behaves like that since the introduction in https://github.com/dotnet/extensions/pull/5290
