Add hash validation support for the clusterResourceWhitelist about argo-cd HOT 2 OPEN

Hi @saltbo, it would seem like this proposal is specifically written to integrate with your internal platform.

the platform automatically sets the hash value of the resource to the project to which it belongs.

Is that process done by an open-source tool? The resourceHashes does not seem to be a standard kubernetes field. If by the project to which it belongs you mean the Argo AppProject, how is that hash generated?

Hi @agaudreault, thanks for your reply.

It's not only for our internal platform, it's a universal solution. We just need to provide a consistent hash function for the K8s resource.

I don't know if there is a similar tool, it would be better if there were. My initial idea is that as long as the file formats are consistent, the hash values can be consistent. We format it the same way and hash it the same way (such as using the sha1 algorithm), so we can get a consistent hash value.
