etcd3/store: support TTL in Create, Update
ref: https://github.com/kubernetes/kubernetes/issues/22448
What's included in the PR?
- Support TTL keys in Create() and Update()
- Simple testing for create
Note
- Have TTL keys in a long window (5min) in one lease. I'm not sure if we should do it right now. We could just implement it as simple as is. Once we have etcd3 work done we could start testing and measuring with some realistic load.

client-gen: use serializer instead of codec for versioned client
For a versioned client, because the output of every client method is a versioned object, so it should use a serializer instead of a codec that does conversion.

genericapiserver: Moving more flags to ServerRunOptions
Moving more apiserver flags to generic api server.
With this change, most of the Config is created in genericapiserver.NewConfig(). The plan is to move everything there.
I didnt touch Storage related params as they are being changed in https://github.com/kubernetes/kubernetes/pull/23208.
And I will handle authz and authn in another PR (need to figure out a few things).

Don't log private SSH key
Log files may have more inclusive permissions than private SSH keys, and as such we should not log the key, even if it looks invalid. I accidentally leaked my key this way when posting e2e test logs.
If it does belong to the device then we make sure we mount the mpio device instead of
the raw device.
Heuristics
Login into /dev/disk/by-path/iqn-example.com.2999 -> /dev/sde
Check if sde existsin in /sys/block/[dm-X]/slaves/xx
If it does mount /dev/[dm-x] which will look like /dev/mapper/mpiodevicename in mount

etcd3/store: watcher implementation
ref: https://github.com/kubernetes/kubernetes/issues/22448
This PR does:
- Provide a watcher that uses etcd v3 API to watch changes via etcd and process them based on existing logic of storage.Interface.Watch(), WatchList().
- By using the watcher, very trivial to implement Watch() and WatchList() in etcd3 storage.Interface implementation.

shared controller informers
Related to https://github.com/kubernetes/kubernetes/issues/14978
This demonstrates how controllers which use an `Informer`, would be able to share the same watch and store. A similar "setup and run" approach could be done for an `IndexInformer` to share that cache. I found adding listeners here to be easier than intercepting at the watch interface (problems with resourceVersion) or the reflector (same plumbing, but you have to fan out to multiple stores).
We could also use the cache we build here to back several of the admission plugins that currently run their own lookup caches today.
If there's interest, I can finish out the `SharedInformer` and switch the low hanging fruit over.

Fix PullImage and add corresponding node e2e test
Fixes#24101. This is a bug introduced by #23506, since ref #23563.
The root cause of #24101 is described [here](https://github.com/kubernetes/kubernetes/issues/24101#issuecomment-208547623).
This PR
1) Fixes#24101 by decoding the messages returned during pulling image, and return error if any of the messages contains error.
2) Add the node e2e test to detect this kind of failure.
3) Get present check out of `ConformanceImage.Remove()` and `ConformanceImage.Pull()`. Because sometimes we may expect error to occur in `PullImage()` and `RemoveImage()`, but even that doesn't happen, the `Present()` check will still return error and let the test pass.
@yujuhong @freehan @liangchenye
Also /cc @resouer, because he is doing the image related functions refactoring.
