Documentation: update docs SetHandler mod_cluster-manager (as opposed to mod_cluster_manager)

In the upstream doc:
http://docs.jboss.org/mod_cluster/1.2.0/html/native.config.html
see the chapter
3.5.14. SetHandler mod_cluster-manager
<Location /mod_cluster-manager>
SetHandler mod_cluster-manager

So I think we need to change the <Location /mod_cluster-manager> to <Location /mod_cluster_manager> to keep consistency? And do not know which one is the correct name ? And looks like the screenshot also shows the mod_cluster-manager.
