The ipallocator was blindly assuming that all errors are retryable, that
causes that the allocator tries to exhaust all the possibilities to
allocate an IP address.
If the error is not retryable this means the allocator will generate as
many API calls as existing available IPs are in the allocator, causing
CPU exhaustion since this requests are coming from inside the apiserver.
In addition to handle the error correctly, this patch also interpret the
error to return the right status code depending on the error type.

* First version of batching w/out signatures.
* First version of pod signatures.
* Integrate batching with signatures.
* Fix merge conflicts.
* Fixes from self-review.
* Test fixes.
* Fix a bug that limited batches to size 2
Also add some new high-level logging and
simplify the pod affinity signature.
* Re-enable batching on perf tests for now.
* fwk.NewStatus(fwk.Success)
* Review feedback.
* Review feedback.
* Comment fix.
* Two plugin specific unit tests.:
* Add cycle state to the sign call, apply to topo spread.
Also add unit tests for several plugi signature
calls.
* Review feedback.
* Switch to distinct stats for hint and store calls.
* Switch signature from string to []byte
* Revert cyclestate in signs. Update node affinity.
Node affinity now sorts all of the various
nested arrays in the structure. CycleState no
longer in signature; revert to signing fewer
cases for pod spread.
* hack/update-vendor.sh
* Disable signatures when extenders are configured.
* Update pkg/scheduler/framework/runtime/batch.go

Remove reference to internal types in kuberc types
* Remove unserialized types from public APIs
Also remove defaulting
* Don't do conversion gen for plugin policy types
Because the plugin policy types are explicitly allowed to be empty, they
should not affect conversion. The autogenerated conversion functions for
the `Preference` type will leave those fields empty.
* Remove defaulting tests

Add comprehensive integration tests covering:
- Peer-aggregated discovery merging across multiple API servers
- CRD/APIService exclusion from peer discovery
- Profile-based content negotiation (nopeer)
- Cache invalidation on local discovery changes
- Request routing to peer servers

Extend Fit and BalancedAllocation PreScore state with the the
allocated state, the list of ResourceSlices and the device class
mapping. Gather these once during PreScore and pass them through
the scoring path instead of re-fetching for every scoring call.
This should speed up scoring of DRA extended resources, lowering
scheduling overhead.

BenchmarkPerfSchedulingExperimental_benchmark_dra_experimental_2025-11-05T07:10:33Z.json
is ignored by perf-dash. It probably needs to be called
BenchmarkPerfScheduling_benchmark_*.
Support for DeviceTaintRules depends on a significant amount of
additional code:
- ResourceSlice tracker is a NOP without it.
- Additional informers and corresponding permissions in scheduler and controller.
- Controller code for handling status.
Not all users necessarily need DeviceTaintRules, so adding a second feature
gate for that code makes it possible to limit the blast radius of bugs in that
code without having to turn off device taints and tolerations entirely.
- Add feature gate to control mutable pod resources for suspended jobs
- Implement validatePodResourceUpdatesOnly function to allow only container resource updates
- Allow resource updates for suspended jobs regardless of whether they have started
- Add comprehensive unit and integration tests for all scenarios including started-then-suspended
- Ensure backward compatibility when feature gate is disabled
This enables users to update container resources on suspended jobs, including jobs that
have previously started and been suspended, while maintaining immutability for all other
pod template fields.
