love the idea, because it also outlines a path on how to contribute and grow inside the project harbor.
Would definitely try to incorporate some harbor related project under the harbor umbrella.

LGTM

@Vad1mo @wy65701436 @stonezdj can we can get this in it's kinda suuuuper old and with the new active sub-projects we need it 100%

@goharbor/all-maintainers can we come to an agreement here? IMO it would make much sense to delegate responsibility to subproject maintainers, we have now more subprojects than when this was created. There are also more coming.

@yanji09 @wy65701436 please approve!

Regarding the subproject of Harbor, I believe it is not just a matter of defining roles. We should provide a comprehensive definition of a subproject, which should include:

1. What is a subproject of Harbor? What criteria should be considered whether a project is to be accepted as a subproject? and How?
2. How do we measure the quality and release standards of a subproject?
3. What is the withdrawal mechanism for a subproject? For instance, in the case of Harbor Operator, how do we assess the contribution of a maintainer if the subproject is decided to be deprecated?

Introducing a new role could be beneficial for the community, but we need to establish a clear process for managing subprojects, which we currently lack.

Before introducing new role, we probably need to clean up the subproject firstly, there are some of them are super inactive.
