tools: xl: add option to run in foreground but still monitor for reboot etc
Split daemonization option out from monitoring a domain for reboot
etc. The 'e' option continues to disable both and a new 'F'(oreground)
option disables only daemonization.
When I'm debugging xl in the foreground this is often the behaviour I
would like.
