[collectd] collectd plugin-specific intervals

+1 from me too.

I'd even ask for a different collection interval per instance, e.g.
maybe a "df" change on /home or /boot is less important to check on
every second than a "df" change on /var/log.

While we are on this topic - until this gets implemented - would it be
possible to work around this by having separate collectd servers for
different intervals?
