Describe the bug

Once #17693 is merged Argo CD will be able to "ignore" arrays. However it is still not possible to ignore individual array elements. In order to fix it Argo CD would need to use strategic merge patch (using built-in k8s schema and dynamic CRD schema)

To Reproduce

Unit tests from #14602 are reproducing behavior.

Expected behavior

It should be possible to ignore different individual array elements.

Version

v2.10.4

If someone attempts to fix it before me. We need to use strategic merge patch here: https://github.com/argoproj/argo-cd/pull/17693/files#diff-627c32a4f31d0f97e6ddc1f19ab3add7fb7791e0d1b0503d78c6c049e8cb4865R438

Yes @alexmt I was attempting to fix it using strategic merge patch, it works well but only supports native k8s resources. Do you have any idea how it could work for custom resources?

[saumeya]

This issue is partially fixed by PR - #17693 (comment) , fix is only needed for custom resources now.
