## What this PR does Many resources created as part of managed apps in cozystack (pods, secrets, etc) do not carry predictable labels that unambiguously indicate which app originally triggered their creation. Some resources are managed by controllers and other custom resources and this indirection can lead to loss of information. Other controllers sometimes simply do not allow setting labels on controlled resources and the latter do not inherit labels from the owner. This patch implements a webhook that sidesteps this problem with a universal solution. On creation of a pod/secret/PVC etc it walks through the owner references until a HelmRelease is found that can be matched with a managed app dynamically registered in the Cozystack API server. The pod is mutated with labels identifying the managed app. ### Release note ```release-note [cozystack-controller] Add a mutating webhook to identify the Cozystack managed app that ultimately owns low-level resources created in the cluster and label these resources with a reference to said app. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Adds an admission webhook that injects application lineage labels on resource create/update for improved observability and ownership tracing. - Adds a runtime-updatable mapping for resolving HelmRelease → application, and registers both the lineage controller and webhook during startup. - Adds Deployment, Service, and cert-manager templates to enable and secure the webhook (in-cluster TLS, service routing). - **Tests** - Adds a test to exercise lineage traversal and validate ownership-graph resolution and labeling. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
