This change updates the REST mapper used by all admission plugins to
be backed by cached discovery information. This cache is updated
every ten seconds via a post start hook and will not attempt to
update on calls to RESTMapping. It solely relies on the hook to
keep the cache in sync with discovery.
This prevents issues with the OwnerReferencesPermissionEnforcement
admission plugin when it is used with custom resources that set
blockOwnerDeletion.

fix WaitForAttach failure issue for azure disk
**What this PR does / why we need it**:
From v1.10, `devicePath` will be updated due to following code change:
568afb4ecc/pkg/volume/util/operationexecutor/operation_generator.go (L517-L518)
So in v1.10.0, MountVolume.WaitForAttach will fail in the azure disk remount, error logs would be like following:
```
MountVolume.WaitForAttach failed for volume "pvc-f1562ecb-3e5f-11e8-ab6b-000d3af9f967" : azureDisk - Wait for attach expect device path as a lun number, instead got: /dev/disk/azure/scsi1/lun1 (strconv.Atoi: parsing "/dev/disk/azure/scsi1/lun1": invalid syntax)
Warning FailedMount 1m (x10 over 21m) kubelet, k8s-agentpool-66825246-0 Unable to mount volumes for pod
```
This PR does not use `devicePath` anymore since it could be changed, instead, it use `diskController.GetDiskLun(diskName, volumeSource.DataDiskURI, nodeName)` to get disk LUN, this ARM api call would cost about 0.12s
The GCE disk won't have this issue since `devicePath` is not used in [WaitForAttach func](https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/gce_pd/attacher.go#L133), while aws disk is also using `devicePath` in [WaitForAttach func](https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/aws_ebs/attacher.go#L145), I think there is potentical issue for aws_ebs

Fix kubelet flags.
pflag now sets golang flag `Parsed` before parsing flags 1ce0cc6db4. With that, all kubelet flags setting will be skipped.
We initially added `flag.Parsed` check to work around a issue that flags are parsed twice, thus kubelet flags are appended twice.
However, it doesn't seem to be the case now. I removed the `Parsed` check, and kubelet flags are only appended once.
```

Node-level Checkpointing manager: Migrate dockershim and device plugin manager checkpointing
**What this PR does / why we need it**:
This PR abstracts checkpoint manager at kubelet level. Currently, `dockershim`, `deviceplugin` have their own native checkpointing primitives. And most recently `cpumanager` also added package native checkpointing primitives. This adds to the redundancy at implementation level. Also degrades code readability and consistency.
To help this:
1. Checkpointing interface is being abstracted at kubelet level as `checkpointmanager` package.
2. `dockershim` and `deviceplugin` packages are modified to use `checkpointmanager` instead native checkpointing.

Fix user visible files creation for windows

Fix user visible files creation for windows. Without this, [createUserVisibleFiles](https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/util/atomic_writer.go#L415:24) will get linkname with subpath included, and then symlink will fail. This is because "/" is used in pod spec (e.g. `"new/path/data-1"`) while "\" is used on Windows to get linkname.
