Cache::flexible fails with Redis error "Error processing EXEC across the cluster"

Description

We use a Redis Cluster in AWS. After adding Cache::flexibel it fails with a RedisClusterException Error processing EXEC across the cluster (/var/task/vendor/laravel/framework/src/Illuminate/Redis/Connections/Connection.php:116).

I'm not sure yet, why that is, but I assume it is caused by the usage of putMany method in the RedisStore.php. This uses transactions by calling multi() and later exec(). It seems that is not supported in clusters.

Steps To Reproduce

User a Redis cluster as cache store. Add a Cache::flexible to a controller and execute it.

I'm also hitting this issue on Vapor with a Redis 6.x cache.
