make a simple dynamic client that is easy to use
The dynamic client has annoyed me for the last time! The existing one takes arguments at odd levels, requires lots of information to instantiate, does some weird pool thing, and uses unusual types. This creates an interface like this:
```go
type DynamicInterface interface {
ClusterResource(resource schema.GroupVersionResource) DynamicResourceInterface
NamespacedResource(resource schema.GroupVersionResource, namespace string) DynamicResourceInterface
}
type DynamicResourceInterface interface {
Create(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
Update(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
UpdateStatus(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
Delete(name string, options *metav1.DeleteOptions) error
DeleteCollection(options *metav1.DeleteOptions, listOptions metav1.ListOptions) error
Get(name string, options metav1.GetOptions) (*unstructured.Unstructured, error)
List(opts metav1.ListOptions) (*unstructured.UnstructuredList, error)
Watch(opts metav1.ListOptions) (watch.Interface, error)
Patch(name string, pt types.PatchType, data []byte, subresources ...string) (*unstructured.Unstructured, error)
}
```
You create it from just a `rest.Config`, no mapper, no path resolving func, no trying to set up codecs ahead of time, no unnecessary pool. It just works.
I updated the namespace controller to use it and I updated the existing dynamic client to leverage it so that I get all their tests for "free".
@kubernetes/sig-api-machinery-pr-reviews
@liggitt @smarterclayton @bparees @sttts @ironcladlou I know each of us has struggled with the dynamic client in our time.
@lavalamp @caesarxuchao This is vastly simplifying. I'm eager to drop the old `ClientPool`. client-go will technically have another incompatible semver this release. I'm up for changing it in tree.
```release-note
client-go developers: the new dynamic client is easier to use and the old is deprecated, you must switch.

Only count local mounts that are from other pods
**What this PR does / why we need it**:
In GCE, we mount the same local SSD in two different paths (for backwards compatability). This makes the fsGroup conflict check fail because it thinks the 2nd mount is from another pod. For the fsgroup check, we only want to detect if other pods are mounting the same volume, so this PR filters the mount list to only those mounts under "/var/lib/kubelet".

After K8s 1.10 is upgraded to K8s 1.11 finalizer [kubernetes.io/pvc-protection] is added to PVCs
because StorageObjectInUseProtection feature will be GA in K8s 1.11.
However, when K8s 1.11 is downgraded to K8s 1.10 and the StorageObjectInUseProtection feature is disabled
the finalizers remain in the PVCs and as pvc-protection-controller is not started in K8s 1.10 finalizers
are not removed automatically from deleted PVCs and that's why deleted PVC are not removed from the system
but remain in Terminating phase.
The same applies to pv-protection-controller and [kubernetes.io/pvc-protection] finalizer in PVs.
That's why pvc-protection-controller is always started because the pvc-protection-controller removes finalizers
from PVCs automatically when a PVC is not in active use by a pod.
Also the pv-protection-controller is always started to remove finalizers from PVs automatically when a PV is not
Bound to a PVC.

This commit adds a binding error message for volumeMode:Block
unsupported case.
With this message, users can understand why PV is not bound to
PVC on both dynamic provisioning and manually creating volume.
This patch works as follows:
- In syncVolume, before adding the claim to claimQueue, check if
there is a volumeMode mismatch, and if there is, record the
event for both pv and pvc and skip adding to the queue.

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`.

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

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.

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.

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.

Task 2: Schedule DaemonSet Pods by default scheduler.
Signed-off-by: Da K. Ma <klaus1982.cn@gmail.com>
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
part of #59194https://github.com/kubernetes/features/issues/548
**Release note**:
```release-note
When ScheduleDaemonSetPods is enabled, the DaemonSet controller will delegate Pods scheduling to default scheduler.
```
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:
