Enhance Attribute "messaging.url"

[Rick-Lee137]

Is your feature request related to a problem? Please describe.
"messaging. url" is an attribute that describes the connection string in Messaging System. specification
But, it is unrealized until now.
In my scene, Spans created by opentelemetry-java-instrumentation are used to graph the server-map which describes the dependencies between services. So far The Node indicated Messaging System is grouped by topic. actually, It will group by broker's cluster address and topic. The broker's cluster address can be queried by the attribute "messaging.url" reported by opentelemetry-java-instrumentation.
