Integrate argocd-image-updater feature into argocd

[AnthonyWC]

Hi folks,

I'd like to propose that argocd-image-updater to be integrated/merged into argoCD main as an integrated feature (like how argocd-notifications used to a separate project and now has been integrated into core.

I think this will give this project much needed resource as currently most of the code base is really just contributed by one sole dev (original author).

Please give this a thumb up if you'd like to see this integrated into argoCD main or suggest some other alternative to give this project more resources.

Totally agreed ! This is a great project and really helps me manage my projects.

Since all other components were merged, this project should follow and hopefully get the attention it deserves.

Wdyt @jannfis ?
