allow fallthrough handling from go-restful routes
This sets up the gorestful routes to fall through to a default handler and reorders the API to be ahead of the other endpoints. This makes it possible to cleanly support cases of "match, fail, try this other handler" which we'll need for API server composition.

add local option to APIService
APIServices need an option to avoid proxying in cases where the groupversion is handled later in the chain. This will allow a coherent and complete set of APIServices, but won't require extra connections.

use separate scheme to serve the kube-aggregator
This removes a hack which used the client scheme to serve the kube-aggregator. This switches it to run from its own scheme.

Many of our core loops rotate around JitterUntil, which means we create
a lot of garbage at steady state for timers. Add proper timer reuse in
this loop.

Remove 'all namespaces' meaning of empty list in PodAffinityTerm
Removes the distinction between `null` and `[]` for the PodAffinityTerm#namespaces field (option 4 discussed in https://github.com/kubernetes/kubernetes/issues/43203#issuecomment-287237992), since we can't distinguish between them in protobuf (and it's a less than ideal API)
Leaves the door open to reintroducing "all namespaces" function via a dedicated field or a dedicated token in the list of namespaces
Wanted to get a PR open and tests green in case we went with this option.
Not sure what doc/release-note is needed if the "all namespaces" function is not present in 1.6

Update hack scripts to use godep v79 and ensure_godep_version
**What this PR does / why we need it**:
Based on #42965 and https://github.com/kubernetes/kubernetes/pull/42958#discussion_r105568318, this pins the godep version at v79, which should fix some issues when running godep in go1.8 local environments.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#42817
**Special notes for your reviewer**:
This should likely get the v1.6 milestone so that it can be merged into master. While I'm setting a default godep version, I'm continuing to use the local pins per this comment: https://github.com/kubernetes/kubernetes/pull/42965#issuecomment-285962723 .

Fix DefaultTolerationSeconds admission plugin
DefaultTolerationSeconds is not working as expected. It is supposed to add default tolerations (for unreachable and notready conditions). but no pod was getting these toleration. And api server was throwing this error:
```

Mar 08 13:45:39 fedora25 hyperkube[32070]: E0308 13:45:39.754669 32070 admission.go:71] expected pod but got Pod

```
The reason for this error is that the input to admission plugins is internal api objects not versioned objects so expecting versioned object is incorrect. Due to this, no pod got desired tolerations and it always showed:
```
Tolerations: <none>
```
After this fix, the correct tolerations are being assigned to pods as follows:
```
Tolerations: node.alpha.kubernetes.io/notReady=:Exists:NoExecute for 300s
node.alpha.kubernetes.io/unreachable=:Exists:NoExecute for 300s
```
