Two in-tree places looked for entries with a literal string lookup. This
compared a QualifiedName from a current slice against a QualifiedName from an
allocation result, which is based on some older slice. The literal lookup
breaks if the slices changed from fully-qualified to un-qualified or vice
versa.
The correct approach is to do what lookupAttribute for constraints does: check
both forms. Following the example set by lookupAttribute, fully-qualified is
given precedence in case of a conflict.
Also update tests that toggled these gates off to instead pin the
emulated version to 1.37, where the gates are still unlocked, and
regenerate the feature-gate reference docs.
Kubernetes 1.37 finished the introduction of context-aware client-go APIs.
Components like kube-controller-manager which are meant to support contextual
logging should use those new APIs.
This is not enforced yet because existing code must be updated first. Once
that is done, enforcement of everything touched here can be enabled tree-wide.
Add unit tests for handwritten and declarative validation, controller
logic, metrics, table printer output, controller-manager registration,
etcd storage round-trip, and an integration test for the full RPSR
lifecycle. Also add an e2e test exercising the DRA test driver with
RPSR and the example manifest.
Implement the RPSR controller that watches ResourcePoolStatusRequest
objects and aggregates pool status from DRA drivers. Add the API server
registry (strategy, storage), handwritten validation, RBAC bootstrap
policy for the controller, kube-controller-manager wiring, table
printer columns, and storage factory registration.
