Tomcat Clustering documentation for Geronimo v1 updated

[Dave Colasurdo]

The Geronimo Tomcat clustering documentation has been updated for v1. 
The jvmRoute can now be easily set in config.xml instead of specifying 
it at server startup.

Be aware that this is geronimo Tomcat Clustering which is different than 
WADI.
