cli: add 'activate' menu command for interactive editor (rh #1004883)

Browse Source 
This command allows activating the edited connection.

Monitoring the progress of the activation is a bit complicated by the fact
that the callback activate_connection_editor_cb() is invoked in main loop
thread, and not in the editor thread itself.
