Deployment to stop adding pod-template-hash labels/selector on adoption

**What this PR does / why we need it**: This is a blocker for #55714, because ReplicaSet selector becomes immutable in `apps/v1`. With controller ref, Deployment's ReplicaSets and Pods can avoid fighting with each others without unique label/selector (pod-template-hash), so it's safe to stop adding hash label/selector on adoption. 

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #61433

**Special notes for your reviewer**: This is a behavioral change to Deployment controller that will affect all versions of Deployment APIs (`apps/v1`, `extensions/v1beta1`, `apps/v1beta1`, `apps/v1beta2`). 

**Release note**:

```release-note
Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).

Use apps/v1 ReplicaSet in controller and tests.

This updates the RS/RC controller and RS integration/e2e tests to use apps/v1 ReplicaSet, as part of #55714.

It does *not* update the Deployment controller, nor its integration/e2e tests, to use apps/v1 ReplicaSet. That will be done in a separate PR (#61419) because Deployment has many more tendrils embedded throughout the system.

```release-note
Conformance: ReplicaSet must be supported in the `apps/v1` version.

Remove method NewCronJobControllerFromClient

**What this PR does / why we need it**:

This method was originally introduced when cronjob was still called scheduledjob: 7a34347f7f
Back then, both init methods had different signatures.

Since the rename to cronjob (41d88d30dd), this method is an alias to the normal initializer, have the same signature and is not used anywhere in the codebase.

Since this method was never actually used for cronjobs, it doesn't seem removing it would need any deprecation notice.

Ignore unready pods when calculating desired replicas

**What this PR does / why we need it**:

This PR causes `GetExternalMetricReplicas` and `GetObjectMetricReplicas` to ignore unready pods when computing the number of desired replicas. If we don't ignore unready pods, there is a risk of overscaling. See the commit messages for examples and implementation info.

Fixes #59975 

**Special notes for your reviewer**:
@MaciekPytel and I consciously chose to save `GetExternalPerPodMetricReplicas` for a separate PR, as we aren't definite on what is the preferred behavior.

**Release note**:

```release-note
Unready pods will no longer impact the number of desired replicas when using horizontal auto-scaling with external metrics or object metrics.

disable DaemonSet scheduling feature for 1.10

The DaemonSet scheduling feature has blocked the alpha CI job being green and is preventing getting good CI signal for v1.10

It still contains pod scheduling races (#61050) and fundamental issues with the affinity terms it creates (#61410)

As such, there is not significant value in having the feature available in 1.10 in the current state

This PR disables the feature in order to regain green signal on the alpha CI job (reverting commits is likely to be more disruptive at this point)

related to https://github.com/kubernetes/kubernetes/issues/61050

```release-note
DaemonSet scheduling associated with the alpha ScheduleDaemonSetPods feature flag has been removed from the 1.10 release. See https://github.com/kubernetes/features/issues/548 for feature status.

Prevent garbage collector from attempting to sync with 0 resources

**What this PR does / why we need it**:
As of #55259 we enabled garbagecollector.GetDeletableResources to return partial discovery results (including an empty set of discovery results).
This had the unintended consequence of allowing the garbage collector to enter a blocked state that can only be fixed by restarting.

From [this comment](https://github.com/kubernetes/kubernetes/issues/60037#issuecomment-372801088):

> 1. The Sync function periodically calls GetDeletableResources
>
> 2. According to the comment above GetDeletableResources, All discovery errors are considered temporary. Upon encountering any error, GetDeletableResources will log and return any discovered resources it was able to process (which may be none)., an error in discovery causes the discovery client to no longer discover resources in the cluster, but instead of failing and returning an error, it simply logs the error as garbagecollector.go:601] failed to discover preferred resources: %vthe server was unable to return a response in the time allotted, but may still be processing the request and returns an empty list of resources
>
> 3. The Sync function, upon recieving an empty resource list from discovery, detects that the resources have changed, and calls resyncMonitors, which calls dependencyGraphBuilder.syncMonitors with map[] as the argument as shown in the log as garbagecollector.go:189] syncing garbage collector with updated resources from discovery: map[], which sets the list of monitors to an empty list because it thinks there are no resources to monitor.
>
> 4. Lastly the Sync function calls controller.WaitForCacheSync, which calls cache.WaitForCacheSync, which will continually retry the garbagecollector.IsSynced function until it returns true, but it will always return false because len(gb.monitors) is 0.

This PR prevents that specific race condition from arising.

When `TaintNodesByCondition` enabled, added `node.kubernetes.io/unschedulable:NoSchedule`
 taint to the node if `spec.Unschedulable` is true.

When `ScheduleDaemonSetPods` enabled, `node.kubernetes.io/unschedulable:NoSchedule` 
toleration is added automatically to DaemonSet Pods; so the `unschedulable` field of 
a node is not respected by the DaemonSet controller.

Backoff only when failed pod shows up

**What this PR does / why we need it**:
Upon introducing the backoff policy we started to delay sync runs for the job when it failed several times before. This leads to failed jobs not reporting status right away in cases that are not related to failed pods, eg. a successful run. This PR ensures the backoff is applied only when `updatePod` receives a failed pod.

d33494d459 GetExternalMetricReplicas ignores unready pods
Similar to the change we made for `GetObjectMetricReplicas` in the
previous commit. Ensure that `GetExternalMetricReplicas` does not
include unready pods when its determining how many replica it desires.
Including unready pods can lead to over-scaling.

We did not change the behavior of `GetExternalPerPodMetricReplicas`, as
it is slightly less clear what is the desired behavior. We did make some
small naming refactorings to this method, which will make it easier to
ignore unready pods if we decide we want to.

7e3bce7b3e GetObjectMetricReplicas ignores unready pods
Previously, when `GetObjectMetricReplicas` calculated the desired
replica count, it multiplied the usage ratio by the current number of replicas.
This method caused over-scaling when there were pods that were not ready
for a long period of time. For example, if there were pods A, B, and C,
and only pod A was ready, and the usage ratio was 500%, we would
previously specify 15 pods as the desired replicas (even though really
only one pod was handling the load).

After this change, we now multiple the usage
ratio by the number of ready pods for `GetObjectMetricReplicas`.
In the example above, we'd only desire 5 replica pods.

This change gives `GetObjectMetricReplicas` the same behavior as the
other replica calculator methods. Only `GetExternalMetricReplicas` and
`GetExternalPerPodMetricRepliacs` still allow unready pods to impact the
number of desired replicas. I will fix this issue in the following
commit.

Do not count failed pods as unready in HPA controller

**What this PR does / why we need it**:
Currently, when performing a scale up, any failed pods (which can be present for example in case of evictions performed by kubelet) will be treated as unready. Unready pods are treated as if they had 0% utilization which will slow down or even block scale up.

After this change, failed pods are ignored in all calculations. This way they do not influence neither scale up nor scale down replica calculations.

 Add test/typecheck, a fast typecheck for all build platforms.

Add test/typecheck, a fast typecheck for all build platforms.

Most of the time spent compiling is spent optimizing and linking
binary code. Most errors occur at the syntax or semantic (type) layers.
Go's compiler is importable as a normal package, so we can do fast
syntax and type checking for the 10 platforms we build on.

This currently takes ~6 minutes of CPU time (parallelized).

This makes presubmit cross builds superfluous, since it should catch
most cross-build breaks (generally Unix and 64-bit assumptions).

Example output:

```$ time go run test/typecheck/main.go
