Update repo-infra bazel dependency and use new gcs_upload rule
This PR provides similar functionality to push-build.sh entirely within Bazel rules (though it relies on gsutil).
It's an alternative to #44306.
Depends on https://github.com/kubernetes/repo-infra/pull/13.

Silence error messages from the docker rmi call we expect to fail
**What this PR does / why we need it**: when we removed `docker tag -f` in #34361 we added a bunch of `docker rmi` calls to preserve behavior for older docker versions. That step is usually a no-op, however, and results in confusing messages like
```
Tagging docker image gcr.io/google_containers/kube-proxy:c8d0b2e7a06b451117a8ac58fc3bb3d3 as gcr.io/kubernetes-release-test/kube-proxy-amd64:v1.5.4
Error response from daemon: No such image: gcr.io/kubernetes-release-test/kube-proxy-amd64:v1.5.4
```
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#42665
**Special notes for your reviewer**: I could probably remove the `docker rmi` calls entirely, though I don't know if folks are still using docker < 1.10. (I think Jenkins still has 1.9.1.)
**Release note**:
```release-note
NONE

This was broken when we moved to the build container, but no one
noticed. We also likely have another bug, which is that protobuf should
hard fail when we have fields that aren't assigned a tag.

Remove the kube-discovery binary from the tree
**What this PR does / why we need it**:
kube-discovery was a temporary solution to implementing proposal: https://github.com/kubernetes/community/blob/master/contributors/design-proposals/bootstrap-discovery.md
However, this functionality is now gonna be implemented in the core for v1.6 and will fully replace kube-discovery:
- https://github.com/kubernetes/kubernetes/pull/36101
- https://github.com/kubernetes/kubernetes/pull/41281
- https://github.com/kubernetes/kubernetes/pull/41417
So due to that `kube-discovery` isn't used in any v1.6 code, it should be removed.
The image `gcr.io/google_containers/kube-discovery-${ARCH}:1.0` should and will continue to exist so kubeadm <= v1.5 continues to work.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
Remove cmd/kube-discovery from the tree since it's not necessary anymore

Rebase kube-proxy and debian-iptables on debian-base
**What this PR does / why we need it**:
Slimmer images are generally preferred, but it's a minor optimization. The larger advantage to this change is the reduced attack surface from removing unnecessary packages, and easier maintenance from sharing a common base image.
Size comparison:
```
gcr.io/google-containers/debian-iptables-amd64:v6 127.9 MB
gcr.io/google-containers/debian-iptables-amd64:v7 45.1 MB
```
**Which issue this PR fixes** https://github.com/kubernetes/kubernetes/issues/40248
**Special notes for your reviewer**:
Tested by deploying to a private test cluster and running the e2es. This will fail the jenkins builds until I push the `gcr.io/google-containers/debian-iptables-amd64:v7` image, which I will do once I have an LGTM.
**Release note**:
```release-note
Clean up the kube-proxy container image by removing unnecessary packages and files.

Standard Debian base image
**What this PR does / why we need it**:
The goal of this new image is to provide a standard base image for Kubernetes system images that require substantial external dependencies (e.g. kube-proxy and fluentd). The image is significantly reduced from the standard `debian:jessie-slim` image (40 MB vs 80 MB), and removes a number of unnecessary dependencies such as e2fsprogs, systemd, and sysv-rc. In the future we may consider further reducing it to the bare minimum to run the package manager, with the requirement that images based on it add all the dependencies they need.
I tested this by rebasing kube-proxy on this image and running the e2e tests. I'm targeting 1.6 for rebasing kube-proxy & fluentd on this.
For the rational behind basing on Debian, see https://github.com/kubernetes/kubernetes/issues/40248#issuecomment-280781931
Largely based off [debian-iptables](https://github.com/kubernetes/kubernetes/tree/master/build/debian-iptables/) and [ubuntu-slim](https://github.com/kubernetes/ingress/tree/master/images/ubuntu-slim).
**Which issue this PR fixes**
https://github.com/kubernetes/kubernetes/issues/40248
**Special notes for your reviewer**:
@luxas Please review the qemu cross-build logic in the Makefile. It's copied from [debian-iptables](https://github.com/kubernetes/kubernetes/blob/master/build/debian-iptables/Makefile), but I'm not sure exactly what it's doing.

bazel: add a config setting to control embedding kubernetes-src.tar.gz
**What this PR does / why we need it**: currently a change anywhere in the tree will cause `kubernetes-src.tar.gz` to need to be regenerated, and thus also the server and node tarballs. All of these operations are slow, so for the sake of developer productivity, only include `kubernetes-src.tar.gz` when we need it (e.g. if we were doing a real release).
I don't have metrics on how much of an effect this has, but I expect it should help incremental builds, especially those that don't affect any node/server targets.
To embed the srcs tarball with this change, you'd run
```console
bazel build //build/release-tars --define EMBED_LICENSE_TARGETS=true
```

```release-note

Add SIGCHLD handler to pause container
**What this PR does / why we need it**: This allows pause to reap orphaned zombies in a shared PID namespace. (#1615)
**Special notes for your reviewer**: I plan to discuss this with SIG Node to ensure compatibility with future runtimes.
**Release note**: This will have no effect until shared PID namespace is enabled, so recommend release-note-none.
This allows pause to reap zombies in the upcoming Shared PID namespace
(#1615). Uses the better defined sigaction() instead of signal() for all
signals both for consistency (SIGCHLD handler avoids SA_RESTART) and to
avoid the implicit signal()->sigaction() translation of various libc
versions.
Also makes warnings errors and includes a tool to make orphaned zombies
for manual testing.
