Unpin channels-redis (ansible#15329)

* unpin channels-redis

The bug that initially caused the upgrade block has been resolved django/channels_redis#332

* replace aioredis Exception with a redis Exception

-The hiredis 2.1.0 release doesn't provide source distribution on PyPI which prevents users to build that python package from the

-Downgrading to 2.0.0 (which provides source distribution) until the channels-redis issue is fixed or a newer hiredis version is
-available on PyPi with source distribution.
