Pointing analytics100{3,4} macs back at their .eqiad.wmnet addresses

These machines were given public IPs as they were previously Kafka brokers.
I want to use them for temporary kafkatee consumer testers now, and I'd
rather they have private IPs before we start saving webrequest logs here.

I will change their entries in site.pp in this commit to avoid conflicts:
