[collectd] Re-reading types.db and/or collectd.conf withouting restart collectd

[Kimo Rosenbaum]

Hello,

Another good habit is to make use of the generic types (derive, gauge, percent, etc), so you don't have to edit types.db that often:

host/my_custom_app/gauge-metric_foo1.rrd
host/my_custom_app/gauge-metric_foo2.rrd
host/my_custom_app/derive-metric_bar1.rrd

Thanks
Kimo
