--------------------------------------------------------------

The attached pull enables deployments of MBeans implementing ServiceMBean, but wrt ServiceMBeanSupport the situation is quite complicated:

- there is an old JBoss Logger exposed (as field and through method), converting to the new Logger will automatically render any MBean that uses it incompatible
- requires org.jboss.mx.util.JBossNotificationBroadcasterSupport, which implementation must be updated too, since it requires missing features
- has pojoX() and AS5 controllers exposed
- has a public method to get missing DeploymentInfo (which in turn needs SARDeployerMBean)
- support of even older ServiceMBeanSupport depends on AS5 ServiceController

Obviously it's not impossible to reimplement any of the missing features, but the class refactor should turn incompatible quite a few of the usages, and if it's not compatible then why not promote the usage of AS7 Services instead...

> It looks like the current SAR deployment code (jboss-as-sar) will deploy simple MBeans just fine.  However, users may expect to be able to deploy older ServiceMBeans from previous Jboss AS versions.  Currently, attempting to do this results in a ClassNotFoundException, since the org.jboss.system.ServiceMBean interface doesn't exist anymore.
> Ideally this would also involve supporting ServiceMBeans that extend org.jboss.system.ServiceMBeanSupport, which also doesn't exist anymore.
