Wildcard Image Aliases in Annotation image-list

[vgiannone3]

Is your feature request related to a problem? Please describe. Presently, in order to allow argocd image updater to update images within my application, I need to go back to the application definition, and add these new images to the image-list annotation. Though this is a relatively simple workflow, it would be great to set once, and let the system recognize the new image, and begin updating automatically.

Describe the solution you'd like I would like to be able to specify a template or wildcard for a set of images within my application which argocd image updater will use to update images.

Describe alternatives you've considered I've reviewed the documentation and have not been able to identify an alternative.
