Add CPU MHz as the value for "node_cpu_info" metric 

For CPUs which don't have an available (or insertable) cpufreq driver,
the /proc/cpuinfo file can sometimes have accurate CPU core frequency
measurements. This change replaces the constant value of "1" for the
"node_cpu_info" metric with the parsed CPU MHz value from
/proc/cpuinfo for each core.
