fix --local flag for kubectl commands
Fixes https://github.com/kubernetes/kubernetes/issues/47079
**Release note**:
```release-note
NONE
```
Fixes the `--local` flag for `kubectl set ...` sub-commands.
**As of the 1.7 release**, `PrinterForCommand` was updated to [use a mapper and typer for unstructured objects](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/util/factory_builder.go#L52), which further prevented the use of `--local` when there was no connection to an api server.
**before** (with no connection to a server)
```
$ kubectl set resources -f pod.json --limits=cpu=200m,memory=512Mi --local
error: unable to connect to a server to handle "pods": Get https://10.13.137.149:8443/api: dial tcp 10.13.137.149:8443: getsockopt: connection refused
```
**after** (with no connection to a server)
```
$ kubectl set resources -f pod.json --limits=cpu=200m,memory=512Mi --local

debian-base: don't remove libcap2
**What this PR does / why we need it**: when I updated the `debian-base` image earlier this week, it apparently removed the libcap2 libraries needed for some dependent images (e.g. fluentd-gcp, #47600).
By holding this package, the library isn't removed from the base image. I've verified by running https://github.com/moul/docker-diff against the `debian-base` image from 2017-02-24.

AWS: Cache instances for ELB to avoid #45050
We maintain a cache of all instances, and we invalidate the cache
whenever we see a new instance. For ELBs that should be sufficient,
because our usage is limited to instance ids and security groups, which
should not change.

I failed terribly at adding a unit test mostly because draining involves discovery for the eviction API and the fake client stuff for discovery are far from functional - will spawn a separate issue about it.

[GCE] Bump GLBC version to 0.9.5
Fixes#47559
```release-note
Bump GLBC version to 0.9.5 - fixes [loss of manually modified GCLB health check settings](https://github.com/kubernetes/kubernetes/issues/47559) upon upgrade from pre-1.6.4 to either 1.6.4 or 1.6.5, or from pre-1.5.8 to 1.5.8.
```
This will create the necessary certificates.
On GCE is will upload those certificates to Metadata.
They are then pulled down on to the kube-apiserver.
They are written to the /etc/src/kubernetes/pki directory.
Finally they are loaded vi the appropriate command line flags.
The requestheader-client-ca-file can be seen by running the following:-
kubectl get ConfigMap extension-apiserver-authentication
--namespace=kube-system -o yaml
Minor bug fixes.
Made sure AGGR_MASTER_NAME is set up in all configs.
Clean up variable names.
Added additional requestheader configuration parameters.
Added check so that if there is no Aggregator CA contents we won't start
the aggregator with the relevant flags.

**Which issue this PR fixes**

**Special notes for your reviewer**:
i was surprised we had not caught this, so if there is an image spec that says leading and trailing whitespace is a good thing, i am open to correction.
i was made aware of downstream users of validate pod template spec that used " " as a special token. as a result, i only do the validation of image name " " in the `Pod` only.

cni: Don't try and map ports with an unset HostPort
The CNI Host function GetPodPortMappings also includes unmapped ports (this is apparently by design). This is normal, and the CNI network plugin invoker should not attempt to map these ports.
