> When viewing the broker diagram with up to one or two master brokers (and
> optionally a slave broker for each) then it is unclear which broker is the
> current broker.
> When there are 3 or more master brokers, the connections between the brokers
> provide a clue (as the one with multiple connections is from the current
> pair). but still it is unclear whether the master broker or the slave broker
> of the current pair is the current broker.
> The PR for this change introduces highlighting of the current node and the
> display of spare slave brokers. Additionally, the previous implementation is
> fixed where needed.
> Details:
> * Remove comments about icons used for address/queue nodes as it does not
> even use an icon (I guess it might have done so in the past);
> * Do not show ":61616" in the broker name, as that is the default;
> * Do not show quotes around addresses and queues;
> * The node-type "ThisBroker" is split into "ThisMasterBroker" and
> "ThisSlaveBroker". "ThisMasterBroker" has the same style as "MasterBroker",
> but just with a black border. "ThisSlaveBroker" has the same style as
> "SlaveBroker", but just with a black border. These styles are applied as
> appropriate;
> * Only show the details when the current broker is selected. Previously the
> details were shown when the corresponding master broker was selected. That
> was correct when the current node was a master, but not when the current
> broker was a slave;
> * When the current broker cannot be found in the reported topology, use the
> current broker-name instead of the text "broker". The brokers that are found
> in the topology are labelled with their hostname, so it is slightly
> different. The hostname does not seem to be available in the information that
> is retrieved for this diagram. But it's too much work to get the actual
> hostname as far as I can tell.
> * When the connectors list shows brokers that are not part of the cluster,
> also show these brokers. the broker is drawn as a white circle with red
> border. Such brokers may be spare slave brokers (when there are more slave
> brokers than master brokers) or brokers that are not connected to yet.
> * Do not show the checkbox controls for which the diagram will not change
> The end-result still looks familiar in most cases, but note the slightly
> different border of the middle master broker:
> !screenshot-1.png!
> In case spare slave brokers are used or when other brokers are just not
> connected:
