Investigate using strings instead of shorts as site-ids. This would eliminate the need for the string-short mapping file and would make life simpler for JDG and EAP as well�.
This would make EAP and JDG configuration simpler, as both configure the mapping from site string (e.g. "sfo") to ID (e.g. 1) on the fly. If we have sites sfo, lon and nyc in 1 config, we might end up with sfo=0, lon=1 and nyc=2. If we only configure lon and nyc in a differemt config, we have lon=0, nyc=1. This means that the second site interprets 0 as lon, although it was effectively sent by sfo.
