Fix autoscaling API documentation
**What this PR does / why we need it**:
This PR fixes the API documentation generated for HorizontalPodAutoscaler resource.
**Which issue(s) this PR fixes**:
The current API doc for `MetricSpec` and `MetricStatus` is confusing. Users get no idea what can be used as the value for the `type` field, because the doc says this:
```
type is the type of metric source. It should match one of the fields below.
```
While acceptable in the source code, it makes no senses when reading the API doc, especially when the "`type`" field is listed as the last row in a table (see: https://kubernetes.io/docs/api-reference/v1.8/#metricspec-v2beta1-autoscaling )
**Special notes for your reviewer**:
This PR makes no changes to the code behavior.
**Release note**:
```release-note

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.
**Release note**:
```release-note
NONE

remove redundant error test case in autoscaling validation
Signed-off-by: allencloud <allen.sun@daocloud.io>
**What this PR does / why we need it**:
I think the error test case I removed is the same as https://github.com/kubernetes/kubernetes/blob/master/pkg/apis/autoscaling/validation/validation_test.go#L393-L412 .
So maybe removal of this part is proper, since it would reduce the codes and save a little bit time in testing.

This commit adds the new API status conditions to the API types.
The field exists as a field in autoscaling/v2alpha1, and is
round-tripped through an annotation in autoscaling/v1.
This commit regenerates the protobuf as per the recent generation
changes (removing erroneous imports, adding k8s.io/metrics), and
syncs the changes to client-go (which also ensures that client-go
protobuf IDL has the correct package names).

Apiregistration v1alpha1→v1beta1
Promoting apiregistration api from v1alpha1 to v1beta1.
API Registration is responsible for registering an API `Group`/`Version` with
another kubernetes like API server. The `APIService` holds information
about the other API server in `APIServiceSpec` type as well as general
`TypeMeta` and `ObjectMeta`. The `APIServiceSpec` type have the main
configuration needed to do the aggregation. Any request coming for
specified `Group`/`Version` will be directed to the service defined by
`ServiceReference` (on port 443) after validating the target using provided
`CABundle` or skipping validation if development flag `InsecureSkipTLSVerify`
is set. `Priority` is controlling the order of this API group in the overall
discovery document.
The return status is a set of conditions for this aggregation. Currently
there is only one condition named "Available", if true, it means the
api/server requests will be redirected to specified API server.
```release-note
API Registration is now in beta.
```
