Was not expecting #1255 to be merged so quickly 🤪. Now the new
serverstats graph has been fully tested and actually works 😉.
This change also doesn't needlessly convert all values to floating
point numbers, instead provides the values to munin in the same format
as they are originally output by chrony.
Also this adds some server stats found in chrony 4.0 (but still works
with 3.4 and probably earlier).
Added chrony_ , a wildcard plugin to track sourcestats per indiviual time source
Added chrony_sourcestats, a plugin that displays the sourcestats characteristics for several timesources in one graph.
Added example graphs for both plugins.
