[collectd] cpufreq extension

[Florian Forster]

Hi Rinigus,

I'd advocate to add this to the "cpufreq plugin".

Guard the new code with a config option, other plugins use "ReportFoo"
for this purpose, so "ReportDistribution true|false" would be a good
choice. Users who are not interested in these metrics can disable them.
Which default, true or false, makes more sense can be discussed.

The "cpu plugin" has an option called "ReportByCpu" which, when set to
"false", will aggregate metrics over all CPUs. Ideally, the "cpufreq
plugin" would have an identical option.

Best regards,
