argocd to automatically pull image on outofsync without syncing?

[UriZafrir]

Motivation

I have an argocd managing many edge computers, running two pods each.
They are connected via SIM to the internet, the connection is not fast, and is not always reliable.
There has been a feature request, that upon argocd application outofsync, argocd will automatically download the new image (latest), without syncing. This is so that the user will have an ability to approve the update and the app will instantly update, having a predownloaded image.
upon the approval, i can use an argo events to sync the application.
From what I know, argocd image updater doesn't have the option to only download the image without syncing, i've also raised an issue there.
