There is upstream work in progress to add support for retrying a sync with a newer commit after a timeout. This feature is to support the upstream work, help get it merged, and include it in the operator. 

Goals

Today if a sync times out, the application goes out of sync. If there have been more commits to the repo since the sync was initiated, it would be useful to have the option for the sync to try again with the latest commit. 

Requirements

Use Cases

Case 03872873, SBB:

We use ArgoCD 2.9.15 for managing OpenShift namespaces. All definitions are Helm charts. As we use git ops only, we want to avoid (and forbid) any manual interaction with ArgoCD, like pressing "sync" or "terminate" buttons. 

Now if there is a problem with the deployment and OpenShift keeps waiting for resources forever (for example due to missconfiguration), ArgoCD is stuck in "syncing" status. Even if you push a new version, ArgoCD is stays busy with syncing the previous version.

We would like to operate ArgoCD in a safe way to protect it from this situation. Ideas we discussed:

1) Allow specification of a timeout, after which the sync stops

2) Allow pushing a new version, which cancels the previous sync
