Find a way to remove cluster id from the cluster config in the repository.xml

The id is the only 'hard coded' part of the config:

<Cluster id="node1">
<Journal class="org.apache.jackrabbit.core.journal.DatabaseJournal">
<param name="revision" value="${rep.home}/revision.log" />
<param name="driver" value="javax.naming.InitialContext"/>
<param name="url" value="java:comp/env/jdbc/clusterDS"/>
<param name="schemaObjectPrefix" value="repository_"/>
<param name="schema" value="mysql"/>
</Journal>
</Cluster>
