Upgrading to 2.0.0 and using redis backend crashing. Seems to need upgraded redis client to 3.4.0

After upgrading to the 2.0.0 image, we saw the following crash in our superset-celery pods:

TypeError: __init__() got an unexpected keyword argument 'username'

After some further investigation, we traced it back to the Redis client needing to accept the username parameter. The support for that was added in this commit which became version 3.4.0. The current docker image is using an older version of the Redis client

Can you open a PR to update the Redis client? Thanks for digging into it!
