bug 1091827 Added hosts file example.  Dropped the folsom- from the hostnames. If this is accepted ill change the network and compute docs as well

Altered to all lowercase.
Dropped node on compute (as per emilien's comments on other draft
thats still out there)
Didnt fix the gateway or dns-nameservers even though still wrong.

Added -priv and -pub and will do the same to my other draft. Never
let it be said that I didnt attempt to "bring the sexy".

Dont see anything under that anne link about anything other than
use lowercase in hostnames.  So not sure if there was any work
behind that comment
