The log4j category for trace logging of message currently org.apache.activemq.transport.TransportLogger:n
this makes it hard to enable the debug logging of just the trace messages since org.apache.activemq.transport is too broad of a category and TransportLogger:n is a variable category name.
We should make it org.apache.activemq.transport.TransportLogger.Connection:n so that it's easier to just enable the logging for this one component. Also log usage of the other request methods.
