Update rules_go, repo-infra, and rules_docker dependencies
**What this PR does / why we need it**: several of our bazel dependencies were getting pretty old, since they required bazel 0.5.4+ but there were various failures if we tried to use them with bazel 0.5.4.
Now that bazel 0.6.0 (and 0.6.1) have been out for a while, we can bump our dependencies and get a number of fixes and new functionality.
x-ref #52677 and others
**Special notes for your reviewer**:
* This will now explicitly require bazel 0.6.0+ to build kubernetes.
* Our staging directories are causing some issues for `gazelle`; it wants to set `importpath = "k8s.io/kubernetes/staging/src/k8s.io/blah"` instead of `importpath = "k8s.io/blah"`. I'm not sure what is the correct way to fix this; what we're doing here is pretty weird and nonstandard. I've used a `sed` substitution for now.
* The `-proto=default` option of `gazelle` has a number of bugs right now (https://github.com/bazelbuild/rules_go/issues/888, https://github.com/bazelbuild/rules_go/issues/900, https://github.com/bazelbuild/rules_go/issues/907), so I am forcing the legacy behavior.

Enable API chunking and promote to beta for 1.9
All list watchers default to using chunking. The server by default fills pages to avoid low cardinality filters from making excessive numbers of requests. Fix an issue with continuation tokens where a `../` could be used if the feature was enabled.
```release-note
API chunking via the `limit` and `continue` request parameters is promoted to beta in this release. Client libraries using the Informer or ListWatch types will automatically opt in to chunking.

code-generator: unify generator main funcs and prepare for launching from one binary
- remove "generated by client-gen with custom arguments" message as this does not
make sense in the times of k8s.io/code-generator
- unify generator main funcs and explicitly call pflag.AddFlags and pflag.Parse. This
will allow to instantiate the generators also from other places.
Requires https://github.com/kubernetes/gengo/pull/80.

Ring buffer for shared informer notifications
**What this PR does / why we need it**:
Improves memory allocation for shared informer listeners. Instead of always appending to the slice use as a ring buffer, avoiding reslice operations as long as there is room in the slice. See https://github.com/kubernetes/kubernetes/pull/47045#issuecomment-317621259 for details. This is a follow up PR for #47045.
Results from BenchmarkListener:
```
Current code (from the #47045):

New code:

Prevent a Kubelet from shutting down when the server isn't responding to
us but we cannot get a new certificate. This allows a cluster to coast
if the master is unresponsive or a node is partitioned and their client
cert expires.

update-staging-godeps: only mangle staging repos in staging Godeps.json
- this re-adds non-staging k8s.io/* repos to the staging Godeps.jsons
- x-outs instead of removing of staging dependencies in order to get a
precise trigger for a complete godep restore+save run in the publisher
bot.
The first breaks k8s.io/kube-aggregator's staging export.
The second potentially leads to inconsistent godeps in our exported staging repos.
