bug: Installation of Fluent-Operator does not install all CRDs

[sherwoodzern]

Describe the issue

Doing a helm install such as:
helm install fluent-operator --create-namespace -n fluent-operator https://github.com/fluent/fluent-operator/releases/download/v3.2.0/fluent-operator.tgz

results in an error in the deployment of the operator and the fluent-bit pods. The following are the errors:

2024-10-15T21:08:13Z ERROR controller-runtime.source.EventHandler if kind is a CRD, it should be installed before calling Start {"kind": "FluentBitConfig.fluentbit.fluent.io", "error": "no matches for kind "FluentBitConfig" in version "fluentbit.fluent.io/v1alpha2""}

To Reproduce

helm install -f custom-values.yaml fluent-operator --create-namespace -n fluent-operator https://github.com/fluent/fluent-operator/releases/download/v3.2.0/fluent-operator.tgz

Expected behavior

I would expect the operator to be successfully installed and the fluent-bit pods to be deployed

Your Environment

- Fluent Operator version: 3.2.0
- Container Runtime: crio
- Operating system: linux
- Kernel version: 8.x

How did you install fluent operator?

helm install -f custom-values.yaml fluent-operator --create-namespace -n fluent-operator https://github.com/fluent/fluent-operator/releases/download/v2.6.0/fluent-operator.tgz

I'm not seeing this error locally with a fresh cluster (KIND) and a helm install:

$ kind create cluster
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.31.0) 🖼
 ✓ Preparing nodes 📦  l
 ✓ Writing configuration 📜 
 ✓ Starting control-plane 🕹️ ^[[A
 ✓ Installing CNI 🔌 
 ✓ Installing StorageClass 💾 
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Not sure what to do next? 😅  Check out https://kind.sigs.k8s.io/docs/user/quick-start/

I think you have an older installation of the operator in your cluster in which case the docs show how to replace the CRDs for it: https://github.com/fluent/fluent-operator?tab=readme-ov-file#deploy-fluent-operator-with-helm
You do have something in your issue saying you installed 2.6.0 which is what makes me think this is it.

Helm by default does not touch existing CRDs - that's a design decision made by the Helm team: https://helm.sh/docs/chart_best_practices/custom_resource_definitions/#some-caveats-and-explanations
