#1603 update the wiki a little bit for the debug profile
add a little toString for debug logging
fixes #1604 (though requires new hawtio release for it to be visible) so we can easily find the debug port of a container with debug enabled (e.g. a java container with the containers-java.debug profile added)
#1604 added debug port to container-info if there is one
#1604 added docs in wiki on how to find the debug port
