Merge #19624: Warn on unknown rw_settings

fa48405ef84985e5a9d38ec38e90d16596ea45b5 Warn 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 (commit fa7dd88b71a1c6641bd450fae29a4a31849b1afd)
