1. 这个接口需要简化一下，常用命令用不了这么多。
2. 需要提供现在已有的Do接口方法，以便开发者使用除了接口方法之外的其他命令。
3. 这个接口需要做一下分类，例如：

type Commander interface{
    KV() KV
    System() System
    // ...
}
type KV interface{
    Get(ctx context.Context, key string) (value string, err error)
    Set(ctx context.Context, key, value string) error
    // ...
}
type System interface{
    Flush(ctx context.Context) error
    // ...
}

4. 这个接口中部分方法不够抽象，存在第三方结构的引用，例如：

XRange(ctx context.Context, stream, start, stop string) ([]redis.XMessage, error)
XRangeN(ctx context.Context, stream, start, stop string, count int64) ([]redis.XMessage, error)
XRevRange(ctx context.Context, stream, start, stop string) ([]redis.XMessage, error)
XRevRangeN(ctx context.Context, stream, start, stop string, count int64) ([]redis.XMessage, error)
XReadStreams(ctx context.Context, streams ...string) ([]redis.XStream, error)

建议这部分方法要么做一下抽象，要么去掉让开发者通过Do方法来调用。

提个小建议,不建议提供Keys接口. O(n)
