Applications can suffer from missing important Keyspace events as described at https://github.com/spring-projects/spring-session/issues/2230.

This adds a caution to the docs to help others avoid running into this problem.

NOTE: When using xref:repositories.adoc[Redis Repositories] with Redis Cluster, make yourself familiar with how to xref:redis/redis-repositories/cluster.adoc[run Redis Repositories on a Cluster].
CAUTION: Relying on keyspace events when using Redis Cluster is discouraged due to https://github.com/spring-projects/spring-data-redis/issues/1111[only being subscribed to events from one random redis node in the cluster].
Using redis without multiple shards avoids this problem.
