"rbd: image xxx is locked by other nodes" is misleading
**What this PR does / why we need it**:
For RWO PV, RBD plugin tries to fence it first, but there are many situations which may cause lock to fail, e.g.
- userSecret is incorrect
- monitor addresses are incorrect or node cannot access ceph cluster temporarily
- image is locked by other nodes
- maybe more...
So, original "image xxx is locked by other nodes" is incorrect in some cases and misleading in diagnosis.
This PR change the error to be correct and not misleading first. We may add detail error descriptions later.
**Special notes for your reviewer**:
New FailedMount event example if RBD plugin cannot lock image:
```
... FailedMount MountVolume.SetUp failed for volume "pvc-ee37a9c8-608e-11e7-b3a7-000c291fbe71" : rbd: failed to lock image kubernetes-dynamic-pvc-ee3b9911-608e-11e7-97b6-000c291fbe71 (maybe locked by other nodes), error exit status 22

Setting default FlexVolume driver directory on COS images.
**What this PR does / why we need it**: The original default FlexVolume driver directory is not writable on COS. A new location is necessary to make FlexVolume work.
This directory doesn't exist by default. FlexVolume users need to create this directory, bind mount it, and remount with the executable permission. The other candidate is /home/kubernetes/bin, but the directory is already getting cluttered. I will submit a different PR for a script that automates this step.

kubeadm: begin polling for bootstrap cluster info immediately
**What this PR does / why we need it**:
This PR changes the behavior of the `kubeadm` loop that polls the API server waiting for discovery information (`cluster-info`). The previous (inadvertent?) behavior was to sleep for `constants.DiscoveryRetryInterval` (5 seconds) before the first request ([`PollInfinite`](https://godoc.org/k8s.io/apimachinery/pkg/util/wait#PollInfinite) vs. [`PollImmediateInfinite`](https://godoc.org/k8s.io/apimachinery/pkg/util/wait#PollImmediateInfinite)).
After this change, `kubeadm` begins does the first check immediately before it moves into the slower polling mode. This takes around 5 seconds off the average time for a new node to join.
#### Before (~5.5s)
```

remove svg mime type extension
Signed-off-by: sakeven <jc5930@sina.cn>
**What this PR does / why we need it**:
I found that [kubernetes requires go version 1.6 or greater](https://github.com/kubernetes/kubernetes/blob/master/hack/lib/golang.sh#L335).
While the [commit](21e47d831b) which adds "image/svg+xml" type for extension ".svg", has been merged to go from version 1.5 to 1.9beta.
So it's safe to remove code ```mime.AddExtensionType(".svg", "image/svg+xml")```.

fix system language judging bug in loadSystemLanguage
Signed-off-by: allencloud <allen.sun@daocloud.io>
**What this PR does / why we need it**:
This PR removes some unused code in loadSystemLanguage. Since in code `pieces := strings.Split(langStr, ".")`, even `langStr` is an empty string, `piece` is a slice with one element of empty string, so there is no chance that len(pieces) == 0.
According to these, I think it is OK to remove the unused code in loadSystemLanguage.
According to the discuss we had, finally we decided to use a more accurate way to change the code, using `if len(pieces) != 1` to make the decision.

kube-apiserver: tests for aggregation and CRDs via delegation
In our integration tests we do not use the real kube-apiserver setup code, but mock our own. Here I use the actual `cmd/kube-apiserver/app.Run()` func with an testing etcd server. This can test the whole delegation chain of aggregator, apiextensions and kube-apiserver.
