[infinispan-dev] Setting JGroups channel name

[Bela Ban]

If you don't define a logical name, JGroups will pick one for you. The 
name will look like {hostname}-{randomShort}, e.g. mybox-12345.

I recommend a good logical name should include
- the function (e.g. "SessionReplication")
- the location (e.g. "mybox")
- if you have multiple instances running on the same box, maybe an ID

Example: SessionCache-mybox-33
