collector/cpu: split cpu freq metrics into separate collector (#1253)

Browse source 
The cpu frequency information is not always needed and/or available.
This change allows the cpu frequency metrics to be enabled/disabled
separately from the other cpu metrics, and also prevents a frequency
metric failure (such as a parse error) from failing the main cpu
collector.

Fixes #1241
