Bump lib-common to a revision that provides the reusable deployment.IsReadyForInput / statefulset.IsReadyForInput helpers, which fetch a workload via an uncached reader, check readiness, and confirm the running pods carry a CONFIG_HASH matching the input just computed this reconcile. To use those helpers the reconcilers need an uncached client.Reader, so add APIReader to the shared ReconcilerBase, populated from mgr.GetAPIReader() in NewReconcilerBase. Nova, Cyborg and Placement all embed this struct, so the reader becomes available at every call site with no signature changes. Add an AppliedInputSecretHash field to the Status of every CR reconciled by this operator (Nova, NovaAPI, NovaScheduler, NovaConductor, NovaCell, NovaCompute, NovaMetadata, NovaNoVNCProxy; Cyborg, CyborgAPI, CyborgConductor; PlacementAPI) and regenerate the CRD manifests. This lets each controller report the hash of the specific input secret its workload has demonstrably rolled out with, so parents (and the external control-plane CR) can correlate readiness with applied input instead of trusting a possibly stale ReadyCondition during secret rotation. This commit only adds the field and infrastructure; the controllers are wired up in the following commits. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Every Nova, Cyborg and Placement service controller previously marked its Deployment/StatefulSetReadyCondition true based only on ReadyCount == Replicas && Generation == ObservedGeneration. During a secret rotation that is racy: the workload's ReadyCondition can still read true from before the rotation while the pods have not yet rolled out with the new config, so a stale-true readiness can be reported to the parent. Gate each leaf's readiness on the new lib-common helper (deployment.IsReadyForInput / statefulset.IsReadyForInput) using the uncached APIReader, so the condition only goes true once the running pods carry a CONFIG_HASH matching the input computed this reconcile. At that same point each leaf records util.ObjectHash of the specific input secret it was given in its Status.AppliedInputSecretHash. PlacementAPI has no intermediate child CRs of its own, so this folds its Layer 1 and Layer 2 handling together: it sets AppliedInputSecretHash directly from its own IsReadyForInput confirmation for the external control-plane CR to correlate against. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The Nova, NovaCell and Cyborg parent controllers aggregated child-CR readiness by mirroring the child's ReadyCondition up guarded only by a generation check (Cyborg did not even check that). That inherits the stale-true race: a child can look ready with a pre-rotation config while its pods are still rolling out the new secret, letting the parent report ready prematurely. Each parent now hashes the specific secret it created for a group of children and, for every child, additionally requires child.Status.AppliedInputSecretHash == that hash before treating the child as having applied the current input. Only once all of a parent's children have applied the current input does the parent record its own Status.AppliedInputSecretHash (hashed over its own externally-supplied input secret), so the external control-plane CR can correlate the same way. The Cyborg gates also gain the previously-missing generation check. Correlation is done purely in readiness reporting; the existing flow-control paths that gate config/secret propagation are left untouched, so a rotation still regenerates and propagates config to children (including NovaCell's compute-config regeneration gated on the NoVNCProxy) without being blocked by the applied-hash check. Add envtest rotation-race functional tests at each level (Nova top-level, NovaCell, Cyborg, PlacementAPI): rotate the input secret and assert AppliedInputSecretHash does not advance until every relevant workload has rolled out the new CONFIG_HASH, then assert it does.

Assert the parent hash before simulating rollout readiness.
After lines 459-464 confirm both templates have the new CONFIG_HASH, assert that AppliedInputSecretHash still equals oldHash before these calls. The current Consistently check runs before propagation is confirmed. A controller that advances the parent hash when propagation completes after that two-second window will pass this test.

Assert that the old finalizer remains before rollout readiness.
Both tests first simulate rollout completion and then check that the finalizer is absent. If the controller removes the finalizer immediately after the template hash changes, both tests still pass. Assert that the old secret retains openstack.org/cyborg-ac-consumer after CONFIG_HASH propagation and before simulating readiness.

Ports watcher-operator's readiness/CONFIG_HASH correlation fix (dc8d388)
into nova-operator, using lib-common's reusable IsReadyForInput helpers.
Every CR reconciled by this operator now reports AppliedInputSecretHash in
its status, and both leaf controllers and parent aggregation correlate
readiness with the input actually rolled out, closing the stale-true
readiness race during secret rotation. This is the config-hash foundation
that PR #1180's secret-rotation / consumer-finalizer work can build on.
