[collectd] rrdcached connecting to an IP instead of unix socket

[Poil]

I'm not sure if I've understand what you are doing but

I think with heartbeat you can manage start/stop of rrdcached with a 
different configuration for your rrdcached srv1 and rrdcached srv2 and 
simply listen on the true IP
