As there are now divers shells around such as GoGo (RFC 147), Karaf GShell it will be useful to provide an option for the shell to be used.
This will start up GoGo shell. As this shell should not interfere with Framework provided shell, when using the --shell option the framework shell will be disabled automatically (as if providing --noConsole)
This option will allow one to use his preferred shell across the frameworks.
