Are we aiming for argo 2.9 ?

[crenshaw-dev]

This is still in the proposal stage, I can't imagine it will be in 2.9.

We want to put a lot of careful thought into how we merge this upstream, because we want it to be truly first-class. Other efforts are currently taking priority.

Closing this one as we decided to move in a different path and not merging image updater in Argo CD
