The lineage-controller-webhook makes a lot of outgoing API calls for every event it handles, contributing to a high API server latency, increasing the number of in-flight requests and generally degrading performance. This patch remedies this by separating the lineage component from the cozystack-controller and deploying it as a separate component on all control-plane nodes. Additionally, a new internal label is introduced to track if a resource has already been handled by the webhook. This label is used to exclude such resources from consideration. Addresses #1513. ```release-note [lineage] Break webhook out into a separate daemonset. Reduce unnecessary webhook calls by marking handled resources and excluding them from consideration by the webhook's object selector. ``` Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
