fa48405ef8Warn on unknown rw_settings (MarcoFalke) Pull request description: Log a warning to debug log if unknown settings are encountered. This should probably only ever happen when the software is upgraded. Something similar is already done for the command line and config file. See: * test: Add test for unknown args #16234 (commitfa7dd88b71) ACKs for top commit: ryanofsky: Code review ACKfa48405ef8. Looks good and I could see this being helpful for debugging. Thanks for taking suggestions Tree-SHA512: cec7d88adf84fa0a842f56b26245157736eb50df433db951e622ea07fd145b899822b24cdab1d8b36c066415ce4f0ef09b493fa8a8d691532822a59c573aafa7
