## What this PR does Adds infrastructure support for restricting tenant workloads to specific data centers (or node groups) via SchedulingClass CRs. - Adds `schedulingClass` parameter to the Tenant model, inherited by child tenants (children cannot override parent's scheduling constraints) - Adds `scheduling.cozystack.io/class` label to tenant namespaces - Adds SchedulingClass dropdown to the Tenant creation form in the dashboard - Extends lineage-controller-webhook to inject `schedulerName: cozystack-scheduler` and `scheduler.cozystack.io/scheduling-class` annotation into all Pods in namespaces with the scheduling label - Webhook verifies the referenced SchedulingClass CR exists before injection; if missing (scheduler not installed), pods are left untouched ### Operators without native schedulerName support The following operators do not support `schedulerName` in their CRDs, but are still covered by the webhook-based approach since it mutates pods directly: - etcd-operator - redis-operator (spotahome) - mariadb-operator - clickhouse-operator (altinity) ### Release note ```release-note [scheduler] Add SchedulingClass support for tenant workloads. Administrators can assign a SchedulingClass to a tenant, restricting where its workloads are scheduled. The lineage-controller-webhook injects the custom scheduler into all pods in the tenant namespace. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added a schedulingClass parameter for tenant configuration; it can be set in values, appears in schema/docs, inherits to namespaces, and is included in exported tenant manifests. * When present, the schedulingClass is propagated to namespace metadata and applied to workloads so scheduler selection and scheduling annotations reflect the setting. * **Bug Fixes** * Improved owner-resolution and labeling so resources and scheduling are associated more accurately. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
