[infinispan-dev] RELAY2 using shorts as site-ids

[Bela Ban]

This is re [1].

I want to replace shorts as site-ids with strings. 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.

However, this will make RELAY2 incompatible with previous releases as 
SiteUUID is now different. The change would be in 3.4 (not 3.3.x), and 
as it will be used by Infinispan 6.0, I don't think this should be an 
issue...

Thoughts ?
