feat: implement partial apply

[cwrau]

this allows the user to create for example a HelmRelease for an operator and the corresponding resource in the same commit

TODO:

• tests
• documentation

[cwrau]

Where is the correct place to create/update documentation for this?

And, do I need to commit the updated CRDs?

This is not something that I would be in favor of, we have dependsOn which allows you to properly apply things in order.

This kind of change would require a RFC, you need to find a Flux maintainer to sponsor your proposal, see here the RFC process https://github.com/fluxcd/flux2/tree/main/rfcs.

Yes and no, dependsOn does not support this exact use-case, as that only works with different kustomizations and not within the same kustomization, which forces the user to create a second kustomization just for ordering while the ordering from a users' standpoint is more often than not just noise and more work; having to split changes into multiple commits and waiting for reconciliation or even multiple repos just for ordering is quite the nuisance, especially when dealing with more than a small handful of clusters.

Huh, didn't know of that, then I suppose I'm going to copy my original issue to a discussion
