RBACRegistryMBean (hawtio-system 3.0-M4 API)

All Known Implementing Classes:

RBACRegistry
```
public interface RBACRegistryMBean
```
MBean that optimizes access to Karaf's RBAC services.

When doing client-side initialization, hawtio invokes two time-consuming operations:
- LIST of available MBeans (with metadata consisting in attrs, ops, description
- EXEC for org.apache.karaf.management.JMXSecurityMBean#canInvoke(java.util.Map)
This becomes unacceptable when we have hundreds of similar MBeans (like ActiveMQ queues or Camel components/endpoints/processors/routes/consumers/...

The role of this MBean is to combine LIST+EXEC/RBAC operations into one - and return map that is complete, but optimized (uses shared JSON elements that can be processed by hawtio client app itself).

                                                     throws java.lang.Exception
```
    Returns Map (that can be nicely handled by Jolokia) containing everything that is initially needed by hawtio client application. It's an optimized and dedicated method that runs much faster than sequence of relevant Jolokia operations (LIST+EXEC with maxDepth=7).
