Use Channel.setInfo() to provide data to JGroups probe

Think about ways to take advantage of following from Bela Ban:

Okay, I've added an "info" paremeter to Probe, so you can run

JGroups/bin/probe.sh -timeout 1000 -query info

and this will dump any information that was added via Channel.setInfo(String key,Object val). The val will be written to a StringBuilder, so make sure you place only values into info which have a meaningful toString().

This can be used to dump buddy replication information.

However, any application which has access to a channel can add information which is useful on a probe, e.g.

• JBossCache
  o Version
  o Buddy replication info
  o Number of nodes, attrs
  o Config info
• Clustering
  o Different clusters a node is part of
  o Node name
  o Config info

The Probe utility is quick and dirty and - since it uses IP multicasts - cannot dump more than 65K worth of data, so make sure you don't cram everything in there ...
