--no-header available now for custom-column
Change `CustomColumnsPrinter` to have `noHeader` boolean, also changed `GetPrinter` to receive this bool and pass it through.
One test `TestNewColumnPrinterFromSpecWithNoHeaders` added for checking if there is no headers in output for sure

Allow a FIFO client to requeue under lock
The Pop method should allow a caller to requeue an item while under the
fifo lock, to avoid races on deletes.

Remove unnecessary calls to api.GetReference
These calls are unnecessary, can be removed. `Eventf` and others just call `GetReference` on the object they are passed.

Optimize priorities in scheduler
Ref #28590
It's probably easier to review it commit by commit, since those changes are kind of independent from each other.

Optimizing the processing flow of HandlePodAdditions and canAdmitPod …
Optimizing the processing flow of HandlePodAdditions and canAdmitPod methods. If the following loop body in canAdmitPod method is removed, the detection speed can be improved, and the change is very small.
------
otherPods := []*api.Pod{}
for _, p := range pods {
if p != pod {
otherPods = append(otherPods, p)
}

Fixes bad heuristic when calling "tc show" to check interface
`tc` sometimes returns stuff that has more than 12 words in its response. The heuristic is bad, but this at least fixes the case when `tc` is returning too much.
Fixes#28571.

Add checks in Create and Update Cgroup methods
This PR is connected to upstream issue for adding pod level cgroups in Kubernetes: #27204
Libcontainer currently doesen't support updates to parent devices cgroups. Until we get libcontainer to support skipping devices cgroup we will have that logic on the kubelet side.
This PR includes:
1. Skip the devices cgroup when updating a cgroup. We only update the memory and cpu subsytems.
2. We explicitly pass all the cgroup paths that don't already exist to Apply()
3. Adds an AlreadyExists() method which is a utility function to check if all the subsystems of a cgroup already exist.
On cgroupManager.Update() we only call Set() and cgroupManager.Create() we only call Apply() method

Revert "Mount r/w GCE PD disks with -o discard"
Reverts kubernetes/kubernetes#28448
We need to make sure that we check for compatibility with the discard flag before mounting with it.
