Build a repository to share more specific images

[jieguangzhou]

Dolphinscheduler has a lot of users, many users will build images for their scenario, If we can share high-quality images with each other, anyone can use dolphinscheduler more easily. Here are some examples

After someone shares an image about dolphinscheduler3.1 and DataX, everyone can use the image to run DataX in dolphinscheduler worker in Kubernetes or Docker. Because the image has built most of the environment about DataX runtime.

Every time we need to run a type of task in dolphinscheduler in Kubernetes or Docker, we just start a special worker from the specified image.

I think we can build a high-quality images hub to make everyone use dolphinscheduler more quickly, and more robust because high-quality images come from real scenarios with many users.
