This is required to support the clients generated for `k8s.io/metrics/pkg/apis/metrics`.

Add a server side Get operation
Implement proposal kubernetes/community#363
```release-note
The Kubernetes API supports retrieving tabular output for API resources via a new mime-type `application/json;as=Table;v=v1alpha1;g=meta.k8s.io`. The returned object (if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`.

resolv.conf nameserver line has only one entry, ignore trailing garbage
**What this PR does / why we need it**:
Per the resolv.conf man page "name servers may be listed, one per keyword." Some tools such as udhcpc take advantage of this to append comments to nameserver entries. For example: `nameserver 8.8.8.8 # eth0`. This updates the resolv.conf parser to ignore trailing garbage on nameserver lines.

Set Kubelet Disk Defaults for the 1.7 release
The `--low-diskspace-threshold-mb` flag has been depreciated since 1.6.
This PR sets the default to `0`, and sets defaults for disk eviction based on the values used for our [e2e tests](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/services/kubelet.go#L145).
This also removes the custom defaults for vagrant, as the new defaults should work for it as well.

```release-note
By default, --low-diskspace-threshold-mb is not set, and --eviction-hard includes "nodefs.available<10%,nodefs.inodesFree<5%"

Add TPR to CRD migration helper.
This is a helper for migrating TPR data to CustomResource. It's rather hacky because it requires crossing apiserver boundaries, but doing it this way keeps the mess contained to the TPR code, which is scheduled for deletion anyway.
It's also not completely hands-free because making it resilient enough to be completely automated is too involved to be worth it for an alpha-to-beta migration, and would require investing significant effort to fix up soon-to-be-deleted TPR code. Instead, this feature will be documented as a best-effort helper whose results should be verified by hand.
The intended benefit of this over a totally manual process is that it should be possible to copy TPR data into a CRD without having to tear everything down in the middle. The process would look like this:
1. Upgrade to k8s 1.7. Nothing happens to your TPRs.
1. Create CRD with group/version and resource names that match the TPR. Still nothing happens to your TPRs, as the CRD is hidden by the overlapping TPR.
1. Delete the TPR. The TPR data is converted to CustomResource data, and the CRD begins serving at the same REST path.
Note that the old TPR data is left behind by this process, so watchers should not receive DELETE events. This also means the user can revert to the pre-migration state by recreating the TPR definition.

Log an EBS vol's instance when attaching fails because VolumeInUse
Messages now look something like this:
E0427 15:44:37.617134 16932 attacher.go:73] Error attaching volume "vol-00095ddceae1a96ed": Error attaching EBS volume "vol-00095ddceae1a96ed" to instance "i-245203b7": VolumeInUse: vol-00095ddceae1a96ed is already attached to an instance

Migrate kubelet to ConfigMapManager interface and use TTL-based caching manager
Fixes#41379
Sometime ago we moved to a secret manager interface for kubelet to manage secrets.
This PR's first commit moves config map management also to a similar interface.
The second commit adds TTL-based CachingConfigMapManager (similar to CachingSecretManager) and makes kubelet use it.

Improve validation of active deadline seconds
**What this PR does / why we need it**:
Improve validation of active deadline seconds to not allow it to be larger than max uint32.
If users choose a value that is too large, the conversion of that value to a duration in seconds can cause an overflow. I see no practical benefit of having a value larger than uint32 at this time.

Write "kubectl options" help message to stdout, not stderr
Fix a very minor issue causing `kubectl` to write its help messages to `stderr` instead of `stdout`.
Try this:
`kubectl options | grep log`
It should print only the options related to logging, but right now it prints the entire help menu (since it's printing to stderr).
This patch brings us closer to unix convention and reduces user friction.
~~Another use case (if a user can't remember whether it's `-r` or `-R` for recursion):~~
~~`kubectl patch -h | grep recursive`~~
Update: this patch only affects `kubectl options`. The other commands are working as intended.
