Because of the ease of use feature within JBoss clustering that all nodes on the same network will
discover each other and form a clustered partition, you can have problems where clusters are formed
unintentionally.

To simplify this problem we should provide a system property and command line option that lets
all the udp groups used by jboss to be separated.
e.g.
./run.sh -c all -u 228.1.2.4
i.e. all udp is done on address 228.1.2.4

This will be configured using system proprties in the jboss configuration, e.g.
<mbean code="org.jboss.ha.framework.server.ClusterPartition"
name="jboss:service=${jboss.partition.name:DefaultPartition}">

<!-- Name of the partition being built -->
<attribute name="PartitionName">${jboss.partition.name:DefaultPartition}</attribute>
...
<Config>
<UDP mcast_addr="${jboss.partition.udpGroup:228.1.2.3}" mcast_port="45566"

where the -u option sets the jboss.partition.udpGroup system property
