generator should sanitize options ending with the fqdn of the machine

[Gauvain Pocentek]

We use the generator._sanitize_default() method in the openstack-doc-tools package to generate the configuration tables for the config-reference. The neutron_id option (and only this one for now) uses the machine fqdn to generate an id. Sanitizing such values could avoid ending up with "neutron-your.fqdn.here" in the sample files and in documentation.

    generator: sanitize values ending with the fqdn

    Some options (neutron_id in the neutron bigswitch plugin) use the
    hostname/fqdn to generate default values prefixed with a static string.
    This patch handles such options and sanitize the default value by
    replacing the hostname/fqdn with the 'oslo' string.
