Fix openstack logging issues for debug, use stdout for default logging

- Log config for stdout logging provided as well but now configured to be used
- Because of some issues with logdir/log_dir logfile/log_file typos, use both

TODO fix init scripts for quantum & agents to redirect stderr to logfiles and
to not use explicit logfile/logdir/logconfig in daemon launch string

Implements (partially): #FUEL-835, Option 2
