Can we omit this annotation entirely if `.Values.admissionWebhooks.certManager.enabled=false` instead of setting it to `none`?

Hey, i would like to work on this issue.

[TylerHelmuth]

@suyash-811 Great, we should wait until https://github.com/open-telemetry/opentelemetry-helm-charts/pull/1176 is merged.

[suyash-811]

Just saw that the PR merged. I'll update the helm template to add the cert-manager annotation if .Values.admissionWebhooks.certManager.enabled=false

[suyash-811]

I took a look at the template admission-webhooks/operator-webhook-with-cert-manager.yaml. There is an ifblock at the start of the file which also uses the same field from the values file to generate the Webhook configurations (.Values.admissionWebhooks.certManager.enabled).

https://github.com/open-telemetry/opentelemetry-helm-charts/blob/870f23120c43a05f8d431fd8f3534e4af44cc104/charts/opentelemetry-operator/templates/admission-webhooks/operator-webhook-with-cert-manager.yaml#L1-L6

Thus, i am a bit unsure if this is the file that really needs the change, as the file isnt rendered at all when the cert-manager admissionWebhook is disabled. Or maybe i got something wrong? Either way, looking forward to some feedback!

@suyash-811 Look for the other places that use the opentelemetry-operator.webhookCertAnnotation helper template. I believe instead of setting none we can add more template logic to conditionally add the annotation.

This is going to break make update-operator-crds and make check-operator-crds and maybe shouldn't be done until we've got a better way to keep the CRD templates up to date.

[suyash-811]

Ah i see. I'll prepare a PR for this. It can be merged once CRD management is done.
