[FEATURE REQUEST] Support custom Redis cache key or prefix

[shuqingzai]

Is your feature request related to a problem? Please describe.

The asynq queue uses asynq as the RedisKey prefix. If my redis has multiple asynq service tasks, all of them will be merged. I hope that custom key or custom key:asynq can be used as a prefix to distinguish different ones Serve

Describe the solution you'd like

I hope that the configuration can customize the redis key prefix

my redis has multiple asynq service tasks

You could use different redis db id/number (namespace) and create multiple lightweight go-redis connection pools for each of them.

See: #647

We ended up forking because we needed the prefix and Redis Cluster support in the CLI.

我的redis有多个asynq服务任务

您可以使用不同的 redis db id/number（命名空间）并为每个数据库创建多个轻量级 go-redis 连接池。

redis cluster mode can not select db
