Use helm chart for deploying garm-operator

[gustaff-weldon]

What is the feature you would like to have?

Instead of deploying manifests which first have to be processed via envsubst garm-operator could be released as helm chart where all necessary customisations can be done via values.

Anything else you would like to add?

No response

the operator got created with kubebuilder. And kubebuilder is taking care of updating manifests when certain changes in the code happens.

The biggest concern about having a helm-chart as well is the fact, that a helm-chart needs manual maintenance.
We've initially take a look at helmify to generate a helm-chart as well but decided to not use it for now. But this is more a reason from a capacity point of view rather than a "we do not want to have this" reason 😅

FYI: There is currently an ongoing discussion to generate helm charts with kubebuilder (xref: ✨[WIP]feat: Add the proposal about the helm chart autogenerate plugin.). Once this has landed in kubebuilder, i'm sure we will adapt this feature as well.

I think this landed in the master branch: https://github.com/kubernetes-sigs/kubebuilder/tree/master/pkg/plugins/optional/helm

Can hardly wait for the next stable release

yep, i've recently gave them a try but there is still some work to do in kubebuilder to get this working without refactoring stuff in an existing repo.
And kubebuilder has to be build manually as it's not released yet ( my try was more than a month ago)

That's still progress, which is awesome!
