Public bug reported:

The ServiceLauncher/ProcessLauncher code in oslo.services will check a
'log_options' option on start of the service/process and if True (the
default) it will log the config option values.

The nova-api service used to run with eventlet only via oslo.service,
but since Pike we can run nova-api using wsgi (uwsgi, mod_wsgi, etc).
However, the wsgi app doesn't log the config options.

Compare to this ocata nova-api log:

neutron-full/0cd3ce7/logs/screen-n-api.txt.gz

The placement-api wsgi app does log the options, but uses different
logic (it doesn't honor the log_options option):

https://github.com/openstack/nova/blob/16.0.0/nova/api/openstack/placement/wsgi.py#L59

So there are two things to fix here:

1. nova-api should log config options on startup when running under
wsgi.

2. placement-api should check the log_options option rather than the
debug option.
