Write a tutorial for new CAPN users

[Fei-Guo]

We need to provide a document to describe how to launch a pod base control plane from scratch.

Nice, this is going to be a fun one, we gotta instruct folks on how to install clusterctl and then how to install. I wonder if this should be done after we cut a first v0.0.1-alpha release so that we can have clusterctl properly deploy CAPN as a control plane provider and infra provider.

[Fei-Guo]

In my opinion, we should have a tutorial about deploying CAPN before the first release. We can either wait until clusterctl is ready for CAPN before the first release or we can prepare a yaml version tutorial first if the clusterctl support takes longer time.

That's fair, I'll file some issues for generating all the clusterctl needed manifests for CAPN to work with clusterctl.

Hope we can have the tutorial as soon as possible so that users can have a early try ;)
