There are a few places where the Configuring Messaging content is MDB specific. Factor out the content and place in the EJB Guide. Specifically,

1. Identify topics to move. (There should be a handful.)
2. Open new jira for each topic, linking here, and assign to EJB Guide owner. (dmichael@redhat.com)
3. Assist EJB Guide owner with resolution of new jiras
4. Add link in Configuring Messaging to new location in EJB Guide where it makes sense.
