py-celery: updated to 5.1.2

5.1.2
When chords fail, correctly call errbacks.

We had a special case for calling errbacks when a chord failed which assumed \ 
they were old style. This change ensures that we call the proper errback \ 
dispatch method which understands new and old style errbacks, and adds test to \ 
confirm that things behave as one might expect now.

Avoid using the Event.isSet() deprecated alias.

Reintroduce sys.argv default behaviour for Celery.start().

5.1.1
Fix --pool=threads support in command line options parsing.
Fix LoggingProxy.write() return type.
Couchdb key is now always coerced into a string.
grp is no longer imported unconditionally.
This fixes a regression in 5.1.0 when running Celery in non-unix systems.
Ensure regen utility class gets marked as done when concertised.
Preserve call/errbacks of replaced tasks.
Use single-lookahead for regen consumption.
Revoked tasks are no longer incorrectly marked as retried.
5.1.0
celery -A app events -c camera now works as expected.
Bump minimum required Kombu version to 5.1.0.

5.1.0rc1
Celery Mailbox accept and serializer parameters are initialized from configuration.
Error propagation and errback calling for group-like signatures now works as \ 
expected.
Fix sanitization of passwords in sentinel URIs.
Add LOG_RECEIVED to customize logging.
