[jboss-as7-dev] Add Notification support to the domain management API

[Heiko Braun]

If we intend to provide support for polling it means the notifications need to be kept in memory. 

- What constraints do apply in this case? (I.e. TTL and MAX notification count?)  
- How does the design of this approach allow us to transition into a push based mechanism?  

Overall I am not sure a poll based solution adds any value to the current architecture. This is what we already do and it doesn't require any interim format, i.e. we directly poll for the existence of server resources. But maybe I am missing something here?

Regards, Heiko
