Version bump to etcd v3.2.13, grpc v1.7.5
Reapply https://github.com/kubernetes/kubernetes/pull/57160 but with etcd 3.2.13, which includes https://github.com/coreos/etcd/pull/9047 to fix https://github.com/kubernetes/kubernetes/issues/51099.
We need to scalability test this PR before merging it since the previous attempt to version bump to grpc v1.7+ resulted in a scalability test failure after the PR was merged to master, and we don't want to repeat that. No, no we don't.
Thanks @gyuho for fixing the etcd grpc issue and releasing etcd-3.2.13 on short notice.
**Release note**:
```release-note
Upgrade to etcd client 3.2.13 and grpc 1.7.5 to improve HA etcd cluster stability.

This changes the Kubelet configuration flag precedence order so that
flags take precedence over config from files/ConfigMaps.
See #56171 for rationale.
Note: Feature gates accumulate with the following
precedence (greater number overrides lesser number):
1. file-based config
2. dynamic cofig
3. flag-based config

This explicitly registers Kubelet flags from libraries that were
registering flags globally, and stops parsing the global flag set.
In general, we should always be explicit about flags we register
and parse, so that we maintain control over our command-line API.

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
NONE

Version bump to etcd v3.2.11, grpc v1.7.5
Fix https://github.com/kubernetes/kubernetes/issues/56114: Update to etcd client 3.2.11
Version bumps:
- etcd from 3.1.10 to 3.2.11
- grpc from 1.3.0 to 1.7.5
- grpc-gateway from v1.1.0-25-g84398b9 to v1.3.0
TODO:
- [x] Apply etcd [3.2 client upgrade guide](https://github.com/coreos/etcd/blob/master/Documentation/upgrades/upgrade_3_2.md)
- [x] Apply grpc API changes in 1.6.0 and 1.7.0 [release notes](https://github.com/grpc/grpc-go/releases)
- [x] bbolt was pulled in transitively, why? We have tests that embed etcd, so we must vendor the etcd server and all it's dependencies.
- [x] Upgrade to containerd v1.0.0? Currently kubernetes depends on containerd v1.0.0-beta.2-159-g27d450a0 which depends on grpc v1.3.0, but containerd v1.0.0 depends on grpc 1.7.2. Not needed. The containerd grpc upgrade required [no code changes](ce3e32680d).
- [x] Fix all failing tests
- [x] Ensure we can safely upgrade grpc to 1.7.5 given that docker and cAdvisor still depend on grpc 1.3.0 (both in the versions we vend and on master for both projects). Should we hold off on this change until we have a docker release that uses gprc 1.7.x?
- [x] Wait for grpc 1.7.5 to be released (it will include https://github.com/grpc/grpc-go/pull/1747). Once released, bump grpc version in this PR and remove workarounds in `hack/godep-save.sh`.
Transitive dependencies on grpc:
- docker depends on grpc, but according to the package dependency graph (`go list -f '{{ .Deps }}'`) there are no dependencies from kubernetes to grpc via docker packages.
- containerd v1.0.0 depends on grpc 1.7.2, we should upgrade to containerd v1.0.0 soon, this can be done in a separate PR
- cadvisor depends on grpc 1.3.0 on master, it should upgrade it to grpc 1.7.5, this can be done in a separate PR
**Release note**:
```release-note
Upgrade to etcd client 3.2.11 and grpc 1.7.5 to improve HA etcd cluster stability.
