Support Cluster-API standard

[panpan0000]

What would you like to be added:

to implement part or full clusterAPI standard.

Why is this needed:
In Cloud Native World, declarative API is the trend.
I found kubean project already provides k8s-operator for kubespray so far.
Additionally, But if clusterAPI can be supported, it maybe another good thing to community.
Is there any scope conflict or technical obstacle ?

[panpan0000]

relevant to #8753

@panpan0000 Could you describe what feature do you mean Support Cluster-API here?

Do you want to deploy Cluster-API itself from Kubespray?

[panpan0000]

just a raw expectation :

User could interface with cluster-API standard CRD, but the underlaying logic are all implemented by kubespray.
kubespray as an engine of cluster-api.
it might be helpful for baremetal enviroments.

just two cents, not come to implementation solution so far.

I think this is a very valuable work and I am happy to participate.

I think we need design some parts,like

• AnsibleControlPlane.
• AnsibleBootstrap.
• ...

KubeadmControlPlane 设计

Cluster-api working group is thinking about In-place upgrades feature.
kubernetes-sigs/cluster-api#9559.

It's doubtful that Kubespray could (or should) support clusterAPI. We're not a cloud provider, and there is no API running on some server.
It's just a collection of ansible (which main point it to be agentless) roles which you apply to bring-up a cluster.
