The config coverter is available in the library distribution: jboss-datagrid-7.0.0-library/bin/config-converter.sh (or config-converter.bat)

We should document how to use it, especially:
1) how to specify input and output files (the converter transforms the input file to the output file
2) how to extend classpath so that the tool can see custom classes (e.g. when there's something like grouper class="org.infinispan.distribution.groups.KXGrouper" in the input file)
