Options honored only by the Redis backend. The key prefix namespaces all of
a queue's Redis keys, so BullMQ data can coexist with other keys in a shared
keyspace. It is intentionally NOT part of QueueBaseOptions, because it
is a Redis-specific concept: other backends namespace differently (e.g. the
PostgreSQL backend uses a schema) and ignore it.
