Documentation for --server-output, plus fixes after testing

[dmatej]

• Refactoring around GFLauncher and both children
• Fixed printing output for restart-domain
• Fixed links to JPDA
• Improved output of start/restart commands
  • ie. Konsole in KDE now allows to click directly on the admin endpoint link and open it in a default browser
• I did not document other parameters added in More flexibility to control server start #25790 , because it is not much safe to use them as I tried locally and on Windows machines. They might be useful sometimes, however, ie. when we start docker container, and we don't care about the admin port, just about PID. However there we would still use rather start-serv ... it depends, because sometimes I am restarting domain in container, and in such case I prefer asadmin. We have pretty flexible monster ;-)
