remove redundant "version" key property from the ObjectName of the JMX MBeans
-----------------------------------------------------------------------------

                 Key: QPID-2322
                 URL: https://issues.apache.org/jira/browse/QPID-2322
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker, Java Management : JMX Interface
    Affects Versions: 0.6
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.7


Brokers from 0.5 onward have an additional version=X key property in the MBean 
ObjectName. This was added in 0.5 to enable version tracking for the MBeans to 
accomodate compatibility checks where necessary after changes. In 0.6.0.0 a new 
version tracking system was put in place, using the new ServerInformation 
MBean. As such, the version key property in the ObjectName is no longer 
required.

Motivation for removing the key property is that for certain JMX operations 
that require knowing the exact ObjectName of the single remote MBean you wish 
to operate on, you must know the value of the version key, which is different 
on each type of MBean and also differs between releases. Whilst it is possible 
to easily Query the server for this information, the ability to first perform 
this query is not always available to the user (eg for non-bespoke server 
health checks) and as such they need to know the exact value in advance. 
Removing the now-unused version key from the ObjectName will remove this need 
in future broker releases.
