Bump redis dependency to 6.0.0

[sarah-witt]

What does this PR do?

Bumps redis version to 6.0.0: https://github.com/redis/redis-py/releases/tag/v6.0.0
It includes some breaking changes such as removing previously deprecated fields that we supported.

Additionally, removes support for the connection_pool argument as we do not document it and it is has to be a valid ConnectionPool object.
