KEP-2593 proposed to expand the existing node-ipam controller
to be configurable via a ClusterCIDR objects, however, there
were reasonable doubts on the SIG about the feature and after
several months of dicussions we decided to not move forward
with the KEP intree, hence, we are going to remove the existing
code, that is still in alpha.

Have hpa always update both the metrics and replica count. This fix an
edge case behavior bug where the metrics would not be updated if a
custom metrics was unavailable.
* Added locks on request tracker before accessing fields
Unit test StatefulSetAutoDeletePVCEnabled has been
flaking with DATARACE. Added lock on request tracker
before accessing err field.
* Addressed review comments for PR : Added locks on request tracker before accessing fields
- this function is used by other packages and was mistakenly removed
in 397cc73dc9
- let resource quota controller use this constructor instead of an
object instantiation
Volume that failed Detach() should not be marked as attached, CSI
external-attacher is probably still trying to detach it.
Mark it uncertain instead and wait for Detach() to succeed.
This uses the generic ptr.To in k8s.io/utils to replace functions and
code constructs which only serve to return pointers to intstr
values. Other uses of the deprecated pointer package are updated in
modified files.

When the resource claim name inside the pod had some suffix like "1a" in
"resource-1a", the generated name suffix got added directly after that, leading
to "my-pod-resource-1ax6zgt".
Adding another hyphen makes the result more readable: "my-pod-resource-1a-x6zgt".
* Fix a job quota related deadlock
In case ResourceQuota is used and sets a max # of jobs, a CronJob may get
trapped in a deadlock:
1. Job quota for a namespace is reached.
2. CronJob controller can't create a new job, because quota is
reached.
3. Cleanup of jobs owned by a cronjob doesn't happen, because a
control loop iteration is finished because of an error to create a
job.
To fix this we stop early quitting from a control loop iteration when
cronjob reconciliation failed and always let old jobs to be cleaned up.
* Dont reorder imports
* Don't stop requeuing on reconciliation error
Previous code only logged the reconciliation error inside jm.sync() and
didn't return the reconciliation error to it's invoker
processNextWorkItem().
Adding a copy-paste back to avoid this issue.
* Remove copy-pasted cleanupFinishedJobs()
Now we always call jm.cleanupFinishedJobs() first and then
jm.syncCronJob().
We also extract cronJobCopy and updateStatus outside jm.syncCronJob
function and pass pointers to them in both jm.syncCronJob and
jm.cleanupFinishedJobs to make delayed updates handling more explicit
and not dependent on the order in which cleanupFinishedJobs and
syncCronJob are invoked.
* Return updateStatus bool instead of changing the reference
* Explicitly ignore err in tests to fix linter
PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.
The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.
Code that uses the struct definitions needs to be updated.

When someone decides that a Pod should definitely run on a specific node, they
can create the Pod with spec.nodeName already set. Some custom scheduler might
do that. Then kubelet starts to check the pod and (if DRA is enabled) will
refuse to run it, either because the claims are still waiting for the first
consumer or the pod wasn't added to reservedFor. Both are things the scheduler
normally does.
Also, if a pod got scheduled while the DRA feature was off in the
kube-scheduler, a pod can reach the same state.
The resource claim controller can handle these two cases by taking over for the
kube-scheduler when nodeName is set. Triggering an allocation is simpler than
in the scheduler because all it takes is creating the right
PodSchedulingContext with spec.selectedNode set. There's no need to list nodes
because that choice was already made, permanently. Adding the pod to
reservedFor also isn't hard.
What's currently missing is triggering de-allocation of claims to re-allocate
them for the desired node. This is not important for claims that get created
for the pod from a template and then only get used once, but it might be
worthwhile to add de-allocation in the future.
The allocation mode is relevant when clearing the reservedFor: for delayed
allocation, deallocation gets requested, for immediate allocation not. Both
should get tested.
All pre-defined claims now use delayed allocation, just as they would if
created normally.
