expose cluster partition name via some ManagedObject

In the as4 plugin, we exposed the following trait:

<metric property="partitionName" dataType="trait" displayType="summary"
description="the name of the cluster partition this app server instance belongs to"/>

which we obtained via JMX as follows:

private String getPartitionName() {
ObjectNameQueryUtility queryUtility = new ObjectNameQueryUtility(
"jboss:partitionName=%partitionName%,service=DistributedReplicantManager");
try {
List<EmsBean> mBeans = loadConnection().queryBeans(queryUtility.getTranslatedQuery());
if (mBeans.size() == 1) {
if (queryUtility.setMatchedKeyValues(mBeans.get(0).getBeanName().getKeyProperties()))

{ return queryUtility.getVariableValues().get("partitionName"); }

}
} catch (Exception e)

{ log.error("Could not load partition name as connection could not be loaded"); }

return null;
}

We need this value exposed via some ManagedObject so we can provide the same trait in the as5 plugin.
