Ensure log_file is absent, if it should be, and log_dir is set for debug

To ensure services would use separate files for debug, log(_)dir options
should be used explicitly (except glance which have diff configs for api & registry)

FIXME Dirty hack for quantum init scripts

Explicit --log-config option for daemon overrides config file options
and breaks logging (no logging configs should be used for quantum
because of message loss bug)
