Schedule even if extender is not available when using extender
**What this PR does / why we need it**:
When using scheduler extender, if the extender is not available scheduling of all pods fail.
We should let the scheduling happen but display error message that extender is failing.
`IsIgnorable()` is added to extender to indicate: if scheduling of all pods should fail when it's unavailable
**Backward compabtiility:**
We use `IsIgnorable` instead of `IsCritical` so that when this flag is not set, the default value will be `false`, i.e. not ignorable, which consistent with the current behavior in existing extenders.

Wait longer in pod cleanup
I've checked the [garbage collector tests](827b3d77cd/test/e2e/apimachinery/garbage_collector.go (L557)) and usually they're waiting up to a minute to clean the resources. So I'm proposing to use that same values when waiting for the pod cleanup. I was not able to reproduce the problem locally, but from reading the logs it looks like the problem might be with just the timing nothing else.

Make UnstructuredContent return contents without mutating the source
**What this PR does / why we need it**:
This PR solves the issues described in #56316
Before this change:
- A call to `UnstructuredContent()` potentially modified `Object`
- The values returned by `UnstructuredContent()` could be manipulated to modify the value in `Object`. Going through the history it looks like this behavior was added before the addition of `SetUnstructuredContent()`. IMO it makes more sense now to use `SetUnstructuredContent()` or make changes to the exposed `Object` property
- `UnstructuredList` did not implement the behavior described in the godoc. The godoc stated that the value returned should be mutable, but if u.Object == nil the map returned had no effect on Object
With this PR I'm proposing `UnstructuredContent()` returns the data without providing the contract of a mutable map. It also ensures all implementations of the `Unstructured` interface abide by the doc

Fixes#56316

When using custom network with IP-alias, use the former's subnet for the latter too
Currently, when we're using custom subnet and ip-alias simultaneously, the cluster fails to come up.
The reason is because we're creating a subnet in the former with one name, but expecting a differently named subnet for the latter.
This is causing [continuous failures in our 100-node job](https://k8s-testgrid.appspot.com/sig-scalability-gce#gce) where I recently turned both of them on.

that the mapper is passed down as well.

Fix bad column alignment when using custom columns from OpenAPI schema
Columns printed by `kubectl get` weren't aligned properly when they were coming from the OpenAPI schema.
This was caused by `CustomColumnPrinter.PrintObj`, which was creating a new `tabwriter.Writer` instead of re-using the tabwriter received through the `out` method parameter (basically, a tabwriter was writing to another tabwriter). Because the PrintObj flushed the tabwriter after writing each individual line, the column widths would reset.
**What this PR does / why we need it**:
This PR fixes the bad column alignment.
**Which issue(s) this PR fixes**
Fixes#56282
**Special notes for your reviewer**:
I've aligned how `CustomColumnPrinter.PrintObj` handles tabwriter with how `HumanReadablePrinter.PrintObj` does it (see https://github.com/kubernetes/kubernetes/blob/master/pkg/printers/humanreadable.go#L299-L303)
**Release note**:

Ensure /etc/hosts has a header always - Fix conformance test
**What this PR does / why we need it**:
We need to be able to tell if an /etc/hosts in a container has been touched by kubernetes or not (whether we use the host network or not).
We have 2 scenarios where we copy /etc/hosts
- with host network (we just copy the /etc/hosts from node)
- without host network (create a fresh /etc/hosts from pod info)
We are having trouble figuring out whether a /etc/hosts in a
pod/container has been "fixed-up" or not. And whether we used
host network or a fresh /etc/hosts in the various ways we start
up the tests which are:
- VM/box against a remote cluster
- As a container inside the k8s cluster
- DIND scenario in CI where test runs inside a managed container
Please see previous mis-guided attempt to fix this problem at
ba20e63446 In this commit we revert
the code from there as well.
So we should make sure:
- we always add a header if we touched the file
- we add slightly different headers so we can figure out if we used the
host network or not.

Retry node pool deletion in autoscaling tests.
**What this PR does / why we need it**:
Currently, when there is already an operation running on the cluster, the node pool deletion will fail. This will in turn make other tests that try to add extra node pool fail.
With this PR we will retry the node pool deletion operation 3 times over the course of ~15 minutes which will hopefully be enough to finish any operations running on the cluster.
This will deflake autoscaling e2e tests on gke regional clusters.
