celery: log an error for some deprecated config settings
dburi was dropped from templates in
d34a59bfcebb1 and is no longer supported
in Celery 4.
celery.send.task.error.emails will no longer be supported in Celery 4 and was
just removed from the .ini template .
The "serialier" typo was fixed in 8169770a4f2c. It might bite people if they
keep using the wrong spelling.
