Wiki Update for Gcache

[Dave Colasurdo]

Here is an initial stab at documenting how to use Gcache with Geronimo 
for clustering.

http://cwiki.apache.org/confluence/display/GMOxDEV/Geronimo+Clustering+with+Gcache
The article still needs a bit of work and will be updated as the Gcache 
development effort progresses in the sandbox.  Though wanted to share 
the current content with others.

Feedback welcome..

Thanks
