controller: set minReadySeconds in deployment's replica sets
* Estimate available pods for a deployment by using minReadySeconds on
the replica set.
* Stop requeueing deployments on pod events, superseded by following the
replica set status.
* Cleanup redundant deployment utilities

make function ReadDockerConfigFile more flexible
In our code, the public function `ReadDockerConfigFile` looks like not enough flexible:
when I want to use this function to get docker config info from a specific path, I have to call `SetPreferredDockercfgPath`, and then the setting preferredPath will be valid in function `ReadDockerConfigFile`. I know in our code, we call `SetPreferredDockercfgPath` in one place ,then call `ReadDockerConfigFile` in another place, it was not in same context. But it looks like not thread safety.
I think if user who use our code want to get docker config from a specific path, it is reasonable to call directly `ReadDockerConfigFile ` with a dockerconfigPath argument, and it can avoid some scenarios that thread is not safety .
I add a test case for this function.

Update run flags to point to generators docs
@janetkuo you've requested that in https://github.com/kubernetes/kubernetes/pull/32484#issuecomment-246840562 I'm opening this PR but like you I don't like the length of the descriptions already. The other problem with this is that there's not clean docs for a user to figure out what the generators are. I've stumbled upon this several times and I always found myself looking into the code :/ How about adding new flag/subcommand that will give you more information about generators and we'd move all those `--restart` and `--generator` information into specific generator info and present at the top level only general information?

Fix edge case in qos evaluation
If a pod has a container C1 and C2, where sum(C1.requests, C2.requests) equals (C1.Limits), the code was reporting that the pod had "Guaranteed" qos, when it should have been Burstable.

Use same SSH tunnel as kubelet
Provides a secure workaround for #11816 by having kube-apiserver use the same SSH tunnel as the kubelet it is trying to connect to. Use in conjunction with iptables or kubelet `--address=127.0.0.1`. The latter will break heapster.
Will fallback to random behavior if the tunnel cannot be found.

Add global timeout flag
**Release note**:
```release-note
Add a new global option "--request-timeout" to the `kubectl` client
```
UPSTREAM: https://github.com/kubernetes/client-go/pull/10
This patch adds a global timeout flag (viewable with `kubectl -h`) with
a default value of `0s` (meaning no timeout).
The timeout value is added to the default http client, so that zero
values and default behavior are enforced by the client.
Adding a global timeout ensures that user-made scripts won't hang for an
indefinite amount of time while performing remote calls (right now, remote
calls are re-tried up to 10 times when each attempt fails, however, there is
no option to set a timeout in order to prevent any of these 10 attempts from
hanging indefinitely).
**Example**
```
$ kubectl get pods # no timeout flag set - default to 0s (which means no
timeout)
NAME READY STATUS RESTARTS AGE
docker-registry-1-h7etw 1/1 Running 1 2h
router-1-uv0f9 1/1 Running 1 2h
$ kubectl get pods --request-timeout=0 # zero means no timeout no timeout flag set
NAME READY STATUS RESTARTS AGE
docker-registry-1-h7etw 1/1 Running 1 2h
router-1-uv0f9 1/1 Running 1 2h
$kubectl get pods --request-timeout=1ms
Unable to connect to the server: net/http: request canceled while
waiting for connection (Client.Timeout exceeded while awaiting headers)

Pass whole PVC to provisioner plugins
Gluster provisioner is interested in namespace of PVCs that are being provisioned and I don't want to add at as a new field in `volume.VolumeOptions` - it would contain almost whole PVC.
Let's rework `VolumeOptions` and pass direct reference to PVC there instead of some "interesting" fields and let the provisioner to pick information it is interested in.
There was lot of refactoring in volume plugins to apply this change (too many plugins), however the logic is simple and it's all the same in all plugins.

honor SAR verb
Verbs on non-resource requests were dropped. This results in always being denied for all the authorizers I know of, so no unintended exposure, but its still ugly. We should probably pick.

Add 'kubectl set resources'
Add "kubectl set resources" for easier updating container memory/cpu limits/requests (for pods or resources with pod templates).
**Usage**
`kubectl set resources (-f FILENAME | TYPE NAME) ([--limits=LIMITS & --requests=REQUESTS])`
**Examples**
Set a deployments nginx container cpu limits to "200m and memory to "512Mi"
`kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi`
Set the limit and requests for all containers in nginx
`kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi`
Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
`kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml`
Remove limits on containers in nginx
`kubectl set resources deployment nginx --limits=cpu=0,memory=0`

Support trust id as a scope in the OpenStack authentication logic
This patch allows the use of Kubernetes with Keystone trust delegation to avoid passing the user credentials in clear inside the config file : a specific user with delegated rights can be created and used instead.
