What would you like to be added:

Develop a new component for delay queue API.

Choose an open source component or cloud service you like to implement this API.

For example, you can choose any one in the list below:

• RocketMQ
• Active MQ
• Rabbit MQ
• QMQ
• Cloud service provided by Alibaba cloud
• Cloud service provided by AWS
• Cloud service provided by Google cloud
• Cloud service provided by tencent cloud
• Cloud service provided by qiniu cloud
• anything else

What is this API used for?:
DelayQueue is a special kind of message queue, which lets you postpone the delivery of new messages to consumers.
For example, you can invoke this API and tell the message queue "please send this message to the consumers after 5 minutes".

Do I have to use Golang for developing component?

[seeflood]

@DhirajSardar Yes, we have to develop components in golang

I am willing to implement it with RocketMQ

[seeflood]

Thanks @zach030 , long time no see 😆
You can submit an issue to track progress

@seeflood Hi, 目前dapr中的rocketMQ支持的可参数比较少，尚不支持DelayTimeLevel参数，等待这个PR合并之后可以继续rocketMQ延迟队列的开发 dapr/components-contrib#2198

[seeflood]

@zach030 OK. Looks good

Hi, I'm willing to take the RabbitMQ
