Quobyte Volume plugin
@quofelix and myself developed a volume plugin for [Quobyte](http://www.quobyte.com) which is a software-defined storage solution. This PR allows Kubernetes users to mount a Quobyte Volume inside their containers over Kubernetes.
Here are some further informations about [Quobyte and Storage for containers](http://www.quobyte.com/containers)

Display one or many resources.
Possible resource types include (case insensitive): pods (aka 'po'), services (aka 'svc'), deployments (aka 'deploy'),
replicasets (aka 'rs'), replicationcontrollers (aka 'rc'), nodes (aka 'no'), events (aka 'ev'), limitranges (aka 'limits'),
persistentvolumes (aka 'pv'), persistentvolumeclaims (aka 'pvc'), resourcequotas (aka 'quota'), namespaces (aka 'ns'),
serviceaccounts (aka 'sa'), ingresses (aka 'ing'), horizontalpodautoscalers (aka 'hpa'), daemonsets (aka 'ds'), configmaps (aka 'cm'),
componentstatuses (aka 'cs), endpoints (aka 'ep'), petsets (alpha feature, may be unstable) and secrets.
This command will hide resources that have completed. For instance, pods that are in the Succeeded or Failed phases.
You can see the full results for any resource by providing the '--show-all' flag.
By specifying the output as 'template' and providing a Go template as the value
of the --template flag, you can filter the attributes of the fetched resource(s).

Add validation conditions for autoscale
When validate the value of max and min in autoscale.go, it should append all the invalid conditions to errs, and print the value.
resource.Builder should prohibit empty resource names (the error is from
the wrong place) so that commands that work on multiple resources but
not resource types can properly limit errors.
- added warning description regarding terminated objects to `get` long help message
- added printing of warning message in case of `get pods` if there are hidden pods

speed up RC scaler
The RC scaler was waiting before starting the scale and then didn't use a watch to observe the result. That led to longer than expected wait times.
@fabianofranz ptal. You may want to sweep the rest of the file. It could use some tidying with `RetryOnConflict` and `watch.Until`.

Add zsh compatibility note `completion` cmd help
zsh completions are not supported on zsh versions < 5.2.
This patch advices user on supported versions of zsh when using the `completion`
command to avoid potential UX failure.
##### After
`$ kubectl completion -h`
```
Output shell completion code for the given shell (bash or zsh).
This command prints shell code which must be evaluation to provide interactive
completion of kubectl commands.
Examples:
$ source <(kubectl completion bash)
will load the kubectl completion code for bash. Note that this depends on the
bash-completion framework. It must be sourced before sourcing the kubectl
completion, e.g. on the Mac:
$ brew install bash-completion
$ source $(brew --prefix)/etc/bash_completion
$ source <(kubectl completion bash)
If you use zsh*, the following will load kubectl zsh completion:
$ source <(kubectl completion zsh)
* zsh completions are only supported in versions of zsh >= 5.2

return err on `kubectl run --image` with invalid value
When running `kubectl run <configname> --image="Invalid$$%ImageValue%%__"`, a configuration is successfully created with an image name that is not a valid value for an image reference.
This patch validates that the image name is a valid image reference, and returns an error before creating a config if an invalid value is passed.

Fix code generators-- make scheme building composable
I needed to make some changes to make my other refactoring possible and this got rather large.
We now provide a "SchemeBuilder" to help all of the api packages provide their scheme-building functions (addKnownTypes and friends) in a standardized way. This also allows generated deepcopies & conversions to be entirely self contained, the project will now build without them being present (as they can add themselves to the SchemeBuilder). (Although if you actually build without them, you will get reduced performance!)
Previously, there was no way to construct your own runtime.Scheme (e.g., to test), you had to use the api.Scheme object, which has all sorts of non-hermetic cruft in it. Now you can get everything from a package by calling the scheme builder's AddToScheme, including the generated functions, if they are present.
Next steps are to allow for declaring dependencies, and to standardize the registration & install code. (#25434)

Update scale cmd help to display duration "units" in --timeout usage

kubectl config set-crentials: add arguments for auth providers
This PR adds `--auth-provider` and `--auth-provider-arg` flags to the
`kubectl config set-credentials` sub-command.
There's currently no way of interacting with the new auth provider framework added in #23066 through kubectl. You have to render a custom kubeconfig to use them. Additionally `kubectl config set` just sort of craps out when attempting to interact with authentication info objects (#29312).
This is a minimal implementation of allowing `kubect config set-credentials` to set fields for client auth providers.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.

fix annotate.go single resource check
```release-note
Fix issue with kubectl annotate when --resource-version is provided.
```
When using `kubectl annotate` with a `--resource-version` on a resource, such as `kubectl annotate pod <pod_name> --resource-version=1820 description='myannotation'`, the command fails with the error: `error: --resource-version may only be used with a single resource`.
Upon printing the output of `resources` that the annotate command receives from cli args, it prints: `Resources:[pod <pod_name>]`. In other words, it treats the name of the resource as a second resource. This PR addresses this issue by using the resource builder `Singular` flag to determine if only a single resource was passed.

allow watching old resources with kubectl
Right now, one can not watch a resource with kubectl whose resourceVersion is outside the etcd watch window. Specifying resourceVersion=0 returns the current object, then watches from the current index.
This PR changes the logic to use resourceVersion=0, which will work regardless of the resourceVersion of the object, and discard the first event if --watch-only is specified.

Create client from API version passed in config or use default
When creating a client read the `GroupVersion` value passed in the `restclient.Config`. If the passed `GroupVersion` does not match current group or is not enabled fallback to default `GroupVersion` for that group.
