Version: 5.0
Release PR: #5686

Description

Celery 5.0 is the first major version to drop support for Python 2. It supports Python 3.6+.
This version also drops support for the Riak Result Backend since Riak is unmaintained and does not support modern Python versions.

This version also refactors our CLI to use click as we prepare to make Celery fully async since it allows us
to invoke async functions in response to commands using asyncclick.
