use_journal option not available in ocata

[Dr. Jens Harbott]

The config documentation for Nova Ocata lists the "use_journal" option[1], however that option was added to oslo.log only for the Pike cycle[2] in oslo.log==3.24.0. It isn't available e.g. in Ubuntu Ocata UCA with python-oslo.log=3.20.1-0ubuntu1~cloud0.

This seems to be an issue with the docs tools. If I read the documentation correctly, the command to regenerate the config options would be

./autohelp-wrapper -b stable/ocata update nova

but that installs the latest libraries and not the ones from upper-requirements.txt for stable/ocata, in particular I get oslo.log==3.34.0 instead of 3.20.1.

Probably as a consequence of this, the run fails, see http://paste.openstack.org/show/626914/ for a traceback.

    [config] Remove Pike option from Ocata

    Remove an option only supported in Pike. Not regenerating tables
    since Ocata is close to EOL and our Ocata tooling is no longer
    maintained.
