py-redis: updated to 3.4.1

3.4.1
* Move the username argument in the Redis and Connection classes to the
  end of the argument list. This helps those poor souls that specify all
  their connection options as non-keyword arguments.
* Prior to ACL support, redis-py ignored the username component of
  Connection URLs. With ACL support, usernames are no longer ignored and
  are used to authenticate against an ACL rule. Some cloud vendors with
  managed Redis instances (like Heroku) provide connection URLs with a
  username component pre-ACL that is not intended to be used. Sending that
  username to Redis servers < 6.0.0 results in an error. Attempt to detect
  this condition and retry the AUTH command with only the password such
  that authentication continues to work for these users.
* Removed the __eq__ hooks to Redis and ConnectionPool that were added
  in 3.4.0. This ended up being a bad idea as two separate connection
  pools be considered equal yet manage a completely separate set of
  connections.
