• Remove ModuleTemplate Webhook
  With the updated pattern of offering ModuleTemplate, we no longer need to validate it through a webhook. This allows us to fully remove moduletemplate_webhook.go:
  

  lifecycle-manager/api/v1beta2/moduletemplate_webhook.go

  Line 37 in 8097721

  func (m *ModuleTemplate) SetupWebhookWithManager(mgr ctrl.Manager) error {

• Relocate Descriptor Struct
  The Descriptor struct, which currently relies on the ocm library, is declared in the API module. We can move it to the lifecycle-manager module, eliminating the need for ocm in the API module:
  

  lifecycle-manager/api/v1beta2/moduletemplate_types.go

  Line 52 in 8097721

  *compdesc.ComponentDescriptor

Reasons

• Reduce API Module Dependencies: Simplifies maintenance for other modules relying on the API, like runtime-watcher.
• Improve KLM Performance: Removing the webhook increases performance and removes a potential single point of failure from the embedded webhook service.

Acceptance Criteria

• Remove ModuleTemplate Webhook
• Relocate Descriptor Struct
• Adjust the Management Plane Charts repository (values.yaml, validating-webhooks.yaml files)
• Check whether the webhook was dropped after the release

The change should be introduced in 2 steps:

1. Disable the webhook in configuration and release/promote to the landscapes
2. Drop the code from KLM + release new version
