Improved logging message for checking if node is shutdown.
**What this PR does / why we need it**:
The previous error message was "Error getting data for node" which was too broad of a message and not very descriptive. This PR will update it to "Error checking if node is shutdown" so that it is more specific.

volume: decrease memory allocations for debugging messages
**What this PR does / why we need it**:
<img width="1769" alt="screen shot 2018-06-11 at 13 15 31" src="https://user-images.githubusercontent.com/44136/41230128-ebf7233c-6d7e-11e8-899d-6251a5fde236.png">
On large clusters, where the glog is not running on V(5) using the format as: `glog.V(5).Infof(fmt.Sprintf(....))` will cause the code inside `Infof()` to be ran and generate a tons of memory allocations even if the output of those messages are not returned to the console...
This patch should reduce those calls and also the string allocations done by message generation.

improve memory footprint of daemonset simulate
**What this PR does / why we need it**:
This is an alternative for https://github.com/kubernetes/kubernetes/pull/64915 (it might be not needed if that PR will merge)
During memory profiling of OpenShift, we noticed a significant amount of object allocations done by `IsControlledBy()`. @sttts found that the `GetObjectReferences()` method is doing a deep-copy of the object references.
![screen shot 2018-06-08 at 14 22 59](https://user-images.githubusercontent.com/44136/41157922-7af953f2-6b27-11e8-9a16-bda8c3edfe07.png)
This PR simplify the `IsControlledBy()` to just iterate over the ownerRefs, without copying them.

Handle deleted DaemonSet properly
**What this PR does / why we need it**:
After kubectl reapers are removed (#63979) and foreground deletion are used, DaemonSet controller may race with garbage collector when it tries to update DaemonSet status of the DaemonSet being deleted.
Here's what happened:
1. Someone/something performs a foreground deletion on a DaemonSet
1. DaemonSet finalizer and DeletionTimestamp are both set
1. DaemonSet history objects (ControllerRevisions) and pods are being deleted by garbage collector; meanwhile, DaemonSet controller tries to update DaemonSet status.
* Updating DaemonSet status requires constructing DaemonSet history objects, to figure out current revision and which pods do/don't belong to current revision
1. When updating DaemonSet status, DaemonSet controller tries to create a DaemonSet history object that matches current DaemonSet spec
1. Garbage collector then tries to delete that DaemonSet history object. And repeat.
Because we can't make DaemonSet pods be deleted before DaemonSet history objects (DaemonSet history objects don't own DaemonSet pods!), we cannot reliably calculate DaemonSet status without history objects anyways. Therefore, we don't update DaemonSet status for DaemonSet being deleted.
Note that the reason why the kubectl delete hack works is because it forces DaemonSet pods to be removed before history objects.

Never clean backoff in job controller
**What this PR does / why we need it**:
In https://github.com/kubernetes/kubernetes/pull/60985 I've added a mechanism which allows immediate job status update, unfortunately that broke the backoff logic seriously. I'm sorry for that. I've changed the `immediate` mechanism so that it NEVER cleans the backoff, but for the cases when we want fast status update it uses a zero backoff.

Schedule DaemonSet Pods in scheduler.

**What this PR does / why we need it**:
**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 #59194
**Special notes for your reviewer**:
**Release note**:
```release-note
`ScheduleDaemonSetPods` is an alpha feature (since v1.11) that causes DaemonSet Pods
to be scheduler by default scheduler, instead of Daemonset controller. When it is enabled,
the `NodeAffinity` term (instead of `.spec.nodeName`) is added to the DaemonSet Pods;
this enables the default scheduler to bind the Pod to the target host. If node affinity
of DaemonSet Pod already exists, it will be replaced.
DaemonSet controller will only perform these operations when creating DaemonSet Pods;
and those operations will only modify the Pods of DaemonSet, no changes are made to the
`.spec.template` of DaemonSet.
