Separate Tutorial document that emphasizes the declarative deployment example (examples/declarative)

[bcle]

We should add it to the tutorial if there's still one.
In particular, the following commands:

• kubectl apply -f examples/declarative for creating app, appprofile, and workload cluster
• kubectl delete -f examples/declarative for cleaning up

The guide does mention it at the end of installation guide.
https://arlonproj.github.io/arlon/0.10/installation/
Are there any other sections that need to mention declarative examples as well?

It'll be wise to wait for a response on #418 (comment)

I see. Ok, it's not intuitive because it's buried at the end of Installation. I didn't realize we didn't have a dedicated Tutorial article. I propose to change this issue to separate the tutorial from the installation, and emphasize the declarative deployment. The tutorial can be very short.

We have separate pages for installation and tutorial. The link for tutorial is https://arlonproj.github.io/arlon/0.10/gen2_Tutorial/

Examples for creation of profiles and apps should be in the tutorial and not in the installation page, right?

I see the 2 tutorials now, one for gen1 clusters and one for gen2 clusters. But the gen2 cluster tutorial uses gen1 profiles. I think we need just one Tutorial article that demoes all the latest features of the current release, and in an easy-to-use manner. This means combining gen2 clusters with AppProfiles and Apps. The declarative example would be great for that. Cluster overrides should also be included, but as we know, we currently can't include that in the declarative example yet due to #416, but the tutorial can still describe it independently.

We'll also need to find a way to support CAS with the new apps and app-profiles. This will need some manual validation, and at worst some code change too. #424 discusses removing the current profiles and bundles code, I think critical features like CAS should be validated before removing them.

@bcle the kubectl delete command might be a bit of trouble because of CAPA bugs. 🤔

For the delete bug, I'm considering updating the example to use kubeadm (control plane and nodes) instead. It's the most mature provider and I've experienced reliable delete semantics in the past.
