Eoghan Glynn 132c54f173 Add --capture-output option to glance-control.
Fixes bug 923894

Previously all stdout/err from glance services was discarded
if launched via glance-control.

The --capture-output option allows such output to be instead
captured in the syslog.

Non-termination output should be flushed to ensure timely
arrival in /var/log/messages.
