Provide ApplyConfigurations

[cwrau]

What would you like to be added (User Story)?

As an operator I want to provision Clusters via Go using SSA because SSA makes it easier to work together on the same resource, e.g. Clusters which get their controlPlaneEndpoint, controlPlaneRef, infrastructureRef, ... set by another operator (cluster-api).

Detailed Description

As an operator I want to provision Clusters via Go using SSA. As far as I can tell SSA is implemented via ApplyConfigurations.

Therefore, I'd like to have these provided by cluster-api.

Anything else you would like to add?

I've tested adding // +genclient to https://github.com/kubernetes-sigs/cluster-api/blob/main/api/v1beta2/cluster_types.go?plain=1#L1169 which allowed me to generate these configurations from my application, but I'm not sure how to hook into your CI and where to generate the code to, ...

Before thinking about if we should generate and provide generated ApplyConfigurations, there are bugs which need to be resolved in controller-tools:

Note: The new applyconfiguration generator has the following known issues: kubernetes-sigs/controller-tools#1193 kubernetes-sigs/controller-tools#1194

source: https://github.com/kubernetes-sigs/controller-tools/releases/tag/v0.18.0

Let's reconsider after these bugs got fixed.
