Use maven-archetype to speed up developing connectors

Hello, community!

During the process of writing connectors, and documents, and reviewing the code of other contributors, I found that there are actually many common writing methods or paradigms among various connectors.

At present, it may be difficult to abstract it into a public module, but I think it may be possible to define a connector universal template through the "maven archetype", so that connector developers can quickly generate a connector framework using the `mvn` instruction. I assume that it can save more than 70% of development time

I would like to discuss it with you all and find out whether this is valuable, please give your opinion
