Add attachable pvc in use metrics
This metric reports number of PVCs that are in-use in Kubernetes with plugin and node name as dimensions.
This allows us to figure out, how many PVCs each node is using. It is super helpful in figuring out attach/detach issues.

Fix exception detection in new version of fluentd-gcp addon
**What this PR does / why we need it**:
The `detect_exceptions` plugin is used to group log entries that belong to a common exception together into one log message. A [recent change](1ca851baec/cluster/addons/fluentd-gcp/fluentd-gcp-configmap.yaml (L100)) to the configuration modified which field is used for the log message, but this change was not applied to the configuration of the `detect_exceptions` plugin, so currently no collation of exception lines is happening.
This change fixes the issue by changing the field the `detect_exceptions` plugin is using.
**Special notes for your reviewer**:
**Release note**:
```release-note
Fixed exception detection in fluentd-gcp plugin.

Honor custom transport dialer
https://github.com/kubernetes/kubernetes/pull/60012 updated API machinery code to use context dial functions by default, but we should still fall back to honor transport.Dial if set
* SetOldTransportDefaults should not use the default http DialContext if a custom Dial method is already set
* DialerFor should prefer DialContext, but fall back to returning a custom Dial if set before returning nil
```release-note
api-machinery utility functions `SetTransportDefaults` and `DialerFor` once again respect custom Dial functions set on transports

Improve job describe and get output
For get, condense completions and success into a single column, and
print the job duration. Use a new variant of ShortHumanDuration that
shows more significant digits, since duration matters more for jobs.
```
NAME COMPLETIONS DURATION AGE
image-mirror-origin-v3.10-1529985600 1/1 47s 42m
image-mirror-origin-v3.11-1529985600 1/1 74s 42m
image-pruner-1529971200 1/1 60m 4h
```
The completions column can be:
```
COMPLETIONS
0/1 # completions nil or 1, succeeded 0
1/1 # completions nil or 1, succeeded 1
0/3 # completions 3, succeeded 1
1/3 # completions 3, succeeded 1
0/1 of 30 # parallelism of 30, completions is nil
```
Update describe to show the completion time and the duration.
```
Start Time: Mon, 25 Jun 2018 20:00:05 -0400
Completed At: Mon, 25 Jun 2018 21:00:34 -0400
Duration: 60m
```
This is more useful than the current output:
```
NAME DESIRED SUCCESSFUL AGE
image-mirror-origin-v3.10-1529982000 1 1 54m
image-mirror-origin-v3.11-1529982000 1 1 54m

```release-note

Add support for Linux Abstract Socket Namespace for KMS provider plugin.
**What this PR does / why we need it**:
Currently, kube-apiserver and kms-plugin interact via a Unix Domain Socket. The current implementation, assumes that such a Domain Socket is supported via a socket file, which is in turn is supported via a volume shared between kube-apiserver and kms-plugin containers.
However, Linux supports Abstract Socket Namespace, where a socket does not need to be back-up by a file. In golang, such sockets are created by prefixing a socket's name with @.
Benefits of using Linux Abstract Socket Namespace:
1. Don't need to worry about possible collisions with existing files.
2. Simpler configuration of master's manifest - no need to setup a shared volume between kube-apiserver and kms-plugin containers.
3. Don't need to remember to unlink the socket when KMS Plugin shuts down.
4. Creates a possibility to run KMS Plugin without access to file system.
This PR adds the ability to define a KMS endpoint as: unix:///@kms-provider.sock

```
- specify `volume.beta.kubernetes.io/resource-group` in PVC annotations
```
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: pvc-azuredisk
annotations:
volume.beta.kubernetes.io/resource-group: "USER-SPECIFIED-RG"

**Special notes for your reviewer**:
For each test, launch a pod for each node to setup volumes when needed.
It uses `nsenter` to enter into host mount namespace to run commands.
Why using `nsenter` command:
- migrate to use hostexec pod (baseimage: alpine:3.6) busybox `losetup` is hard
- alpine does not contain mkfs.ext4 command
- easier to setup local volumes (no need to mount /tmp, /mnt, /dev/, /sys directories)
- only require hostexec pod contains `nsenter` command
**Release note**:
```release-note
NONE
```
