This adds constants and validation for a new `auth-extra-groups` key on `bootstrap.kubernetes.io/token` secrets. This key allows a bootstrap token to authenticate to extra groups in addition to the `system:bootstrappers` group.
Extra groups are always applied in addition to the `system:bootstrappers` group, must begin with a `system:bootstrappers:` prefix, are limited in length, and are limited to a restricted set of characters (alphanumeric, colons, and dashes without a trailing colon/dash).

GCE: Consume new config value for network project id
This PR will allow users to specify the network's project ID in gce.conf. If it's not specified, it will be filled with `ProjectID`. This means that `network-project-id` is a required field for building a cluster on a shared VPC network. However, this means the field does not need to be specified for GKE clusters on non-shared networks.

ScaleIO: Use VolumeHost.GetExec() to execute stuff in volume plugins
This PR updates ScaleIO volume plugin to use `VolumeHost.GetExec()` to execute utilities like mkfs and lsblk instead of simple `os/exec` + to use a fresh `mounter` for every `SetUp` / `TearDown` calls, as they may be different each time.
This prepares the volume plugin to run these utilities in containers instead of running them on the host + makes the volume plugin more independent and less hardcoded.
See proposal in https://github.com/kubernetes/community/pull/589.
Note that this PR does **not** change place where the utilities are executed - `VolumeHost.GetExec()` still leads directly to `os/exec`. It will be changed when the aforementioned proposal is merged and implemented.
**Special notes for your reviewer**:
* I needed to pass `mount.Exec` interface from the place where it is available down to `SioClient` where it's needed to execute stuff.

default field selectors
We have a lot of code around field selectors that doesn't add much value. Every gettable resources probably wants name and namespace by default and since they all use metav1 (today), we can assign that as a default. If we think we'll always have metav1 style name and namespace, then this makes a reasonable default and you can always set something different.
This removes cruft and avoids the risk of accidentally forgetting a field selector.

RBD Plugin: Log RBD Attach/Mount/Unmout actions in addition to Detach
**What this PR does / why we need it**:
Currently, RBD Plugin can log a info message for a successful action of RBD Unmap, e.g.:
```
I0822 09:32:31.595162 15177 rbd_util.go:349] rbd: successfully unmap device /dev/rbd0
```
This PR adds logs for another three important actions: Attach, Mount and Unmount.
Logging these actions and associated info is *very* useful in diagnosing problems.
**Special notes for your reviewer**:
Example RBD Plugin logs of successful pod volume attaching and mounting:
```
I0822 09:30:27.512015 15177 rbd_util.go:148] lock list output "2017-08-22 09:30:27.493889 7fa4ae3c23c0 -1 auth: unable to find a keyring on /etc/ceph/ceph.client.kube.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin: (2) No such file or directory\n"

Example RBD Plugin logs of successful pod volume detaching and unmouting:
```

```
It does not add too much logs, but admins/ops can know what RBD plugin are doing internally and exact time a RBD image is mapped, mounted or unmounted (in addition to unmapped).

I think RevertPorts() is independent from iptables, and would be used by other proxiers which needs to hold/close local port.
Perhaps we can move RevertPorts() from proxier.go to pkg/proxy/util package so that it can be consumed among different proxiers. And, reduce codes in proxier.go

openapi: Change references to be first-class
**What this PR does / why we need it**:
References in the openapi are currently completely hidden from the
model, and just passed through as we walk the tree. The problem is that
they can have a different description and more importantly, different
extensions.
Change them to be first-class citizen, and fully part of the model. It
means that visitors have to implement one more function and decide if
something specific should be done with references. Validation is updated
to just completely ignore them and passthrough (like it was done
before).

Remove crash loop "detection" from the dynamic kubelet config feature
**What this PR does / why we need it**:
The subfeature was a cool idea, but in the end it is very complex to
separate Kubelet restarts into crash-loops caused by config vs.
crash-loops caused by other phenomena, like admin-triggered node restarts,
kernel panics, and and process babysitter behavior. Dynamic kubelet config
will be better off without the potential for false positives here.
Removing this subfeature also simplifies dynamic configuration by
reducing persistent state:
- we no longer need to track bad config in a file
- we no longer need to track kubelet startups in a file
