Release note

we support redis cluster url.
If redis is a cluster, we need use json array , like
redis.url= '["redis://redis-server:6379/","redis://redis-server:6380/","redis://redis-server:6381/]'

if redis is not a cluster,we need use string like (Same way as before.)
redis.url= 'redis://redis-server:6379/'

Do you think we need to start a redis cluster for running the e2e for cluster sink?
