[collectd] Which plug-ins support collection interval on a per-plugin basis feature introduced from 5.2

*All* the plugins support custom intervals since 5.2.0. This is how you
have to load a plugin with a non-default interval:

  <LoadPlugin df>
    Interval 3600
  </LoadPlugin>

What is a bit confusing, is that some plugins implement this or some
similar behaviour themselves for various reasons.
https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_netapp
is an example of such a plugin.

So writing something like this *could* work for some plugins, but is not
the correct way of using this feature:

  LoadPlugin df
  <Plugin df>
    Interval 3600
  </Plugin>

Could there be some misunderstanding on your side ? Or do you have
reasons to believe there's something wrong with the ethstat, interface
and table plugins and not the others ?
