 Pyrra can be configured to validate SLOs and SLO groups using a webhook admission controller. This is an optional feature that can be enabled by setting the `validatingWebhookConfiguration.enabled` value to `true`. The webhook admission controller will validate SLOs when they are created or updated.
 If the SLO object is invalid, the admission controller will reject the request and provide a reason for the failure. This requires cert-manager to be installed in the cluster. If cert-manager is not installed, the webhook admission controller will not be created.
