Refactor the code, moving the hostpath helper functionality to new
"pkg/utils/hostpath" package. This breaks odd-ish dependency
"pkg/utils" -> "source".
Convert the cpu source to do feature discovery and creation of feature
labels separately.
Move cpuidutils from source/internal to the source/cpu package. Change
the cpuid custom rule to utilize GetFeatures of the cpu source.
Also, add minimalist unit test.
