oslo.log's "debug" option was co-opted to also indicate that the
responses should include more information. A separate config
option should be used instead so that deployers don't mistakenly
expose themselves to security issues.
The debug option still is used for what it does in oslo.log and
how it works on all other projects -- if you're not using a log
config file it sets the base logger to debug.
