Queue and Worker opts processing logic

[arusakov]

Constructing of Queue and Worker are very similar, but:

In Queue constructor you can define sharedConnection & blockingConnection property from outside (https://github.com/taskforcesh/bullmq/blob/master/src/classes/queue.ts#L109-L117):

super(
      name,
      {
        sharedConnection: isRedisInstance(opts?.connection),
        blockingConnection: false,
        ...opts,
      },
      Connection,
    );

But in Worker you can not (https://github.com/taskforcesh/bullmq/blob/master/src/classes/worker.ts#L163-L171):

super(
      name,
      {
        ...opts,
        sharedConnection: isRedisInstance(opts.connection),
        blockingConnection: true,
      },
      Connection,
    );

What's the point? Is it bug? SharedConnection & BlockingConnection must always stick together?
