Serve OpenAPI spec with single /openapi/v2 endpoint
**What this PR does / why we need it**:
We are deprecating format-separated endpoints (`/swagger.json`, `/swagger-2.0.0.json`, `/swagger-2.0.0.pb-v1`, `/swagger-2.0.0.pb-v1.gz`) for OpenAPI spec, and switching to a single `/openapi/v2` endpoint in Kubernetes 1.10. The design doc and deprecation process are tracked at: https://docs.google.com/document/d/19lEqE9lc4yHJ3WJAJxS_G7TcORIJXGHyq3wpwcH28nU
Requested format is specified by setting HTTP headers
header | possible values
-- | --
Accept | `application/json`, `application/com.github.proto-openapi.spec.v2@v1.0+protobuf`
Accept-Encoding | `gzip`
This PR changes dynamic_client (and kubectl as a result) to use the new endpoint. The old endpoints will remain in 1.10 and 1.11, and get removed in 1.12.

Update bazelbuild/rules_go, kubernetes/repo-infra, and gazelle dependencies
**What this PR does / why we need it**: updates our bazelbuild/rules_go dependency in order to bump everything to go1.9.4. I'm separating this effort into two separate PRs, since updating rules_go requires a large cleanup, removing an attribute from most build rules.

don't stop informer delivery on error
If an informer delivery fails today, we stop delivering to it entirely. The pull updates the code to skip that particular notification, delay, and continue delivery with the next time.

Bump rules_go and build "static" binaries in pure Go mode
**What this PR does / why we need it**: uses latest set of enhancements in bazelbuild/rules_go to properly build the "static" Go binaries using pure Go (i.e. `CGO_ENABLED=0`), and to support cross compilation of these binaries. Cross compilation of cgo-enabled binaries is still not supported.
Also depends on https://github.com/kubernetes/repo-infra/pull/52, and requires bazel 0.8+ (which is not yet enabled in CI for kubernetes/kubernetes).
Note that for proper cross compilation we'll also need to remove the hardcoded "linux-amd64" that's strewn about several `BUILD` files.
**Release note**:
```release-note
NONE
```
