Add test/typecheck, a fast typecheck for all build platforms.
Add test/typecheck, a fast typecheck for all build platforms.
Most of the time spent compiling is spent optimizing and linking
binary code. Most errors occur at the syntax or semantic (type) layers.
Go's compiler is importable as a normal package, so we can do fast
syntax and type checking for the 10 platforms we build on.
This currently takes ~6 minutes of CPU time (parallelized).
This makes presubmit cross builds superfluous, since it should catch
most cross-build breaks (generally Unix and 64-bit assumptions).
Example output:
```$ time go run test/typecheck/main.go

Remove old featureGate flag in Readme
**What this PR does / why we need it**:
This PR corrects the Readme for ipvs mode: https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/README.md. `kubeadm init` doesn't support the `--feature-gates=SupportIPVSProxyMode=true` flag anymore since IPVS is in beta and not alpha anymore.
```
sudo kubeadm init --help
Run this command in order to set up the Kubernetes master.
Usage:
kubeadm init [flags]
Flags:
--apiserver-advertise-address string The IP address the API Server will advertise it's listening on. Specify '0.0.0.0' to use the address of the default network interface.
--apiserver-bind-port int32 Port for the API Server to bind to. (default 6443)
--apiserver-cert-extra-sans stringSlice Optional extra Subject Alternative Names (SANs) to use for the API Server serving certificate. Can be both IP addresses and DNS names.
--cert-dir string The path where to save and store the certificates. (default "/etc/kubernetes/pki")
--config string Path to kubeadm config file. WARNING: Usage of a configuration file is experimental.
--cri-socket string Specify the CRI socket to connect to. (default "/var/run/dockershim.sock")
--dry-run Don't apply any changes; just output what would be done.
--feature-gates string A set of key=value pairs that describe feature gates for various features. Options are:
CoreDNS=true|false (ALPHA - default=false)
DynamicKubeletConfig=true|false (ALPHA - default=false)
SelfHosting=true|false (ALPHA - default=false)
StoreCertsInSecrets=true|false (ALPHA - default=false)
--ignore-preflight-errors stringSlice A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
--kubernetes-version string Choose a specific Kubernetes version for the control plane. (default "stable-1.9")
--node-name string Specify the node name.
--pod-network-cidr string Specify range of IP addresses for the pod network. If set, the control plane will automatically allocate CIDRs for every node.
--service-cidr string Use alternative range of IP address for service VIPs. (default "10.96.0.0/12")
--service-dns-domain string Use alternative domain for services, e.g. "myorg.internal". (default "cluster.local")
--skip-token-print Skip printing of the default bootstrap token generated by 'kubeadm init'.
--token string The token to use for establishing bidirectional trust between nodes and masters.
--token-ttl duration The duration before the bootstrap token is automatically deleted. If set to '0', the token will never expire. (default 24h0m0s)
```
**Special notes for your reviewer**:
Used kubeadm version:
```bash
sudo kubeadm version
kubeadm version: &version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"d2835416544f298c919e2ead3be3d0864b52323b", GitTreeState:"clean", BuildDate:"2018-02-07T11:55:20Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}

Ts is go/types forked from go@236abdb46b (just after 1.10) and
cherry-picked go@1006f703ffc, which fixes https://github.com/golang/go/issues/23712.
It can be removed when all builders are >= go1.11.
kube-controller-manager defaults --leader-elect to true. We should
do the same for kube-scheduler. kube-scheduler used to have this
set to true, but it got lost during refactoring:

don't (remote) cache release-tars
**What this PR does / why we need it**: Disables Bazel *remote* caching for release tarballs. These are large, low hit rate build outputs. Before we enable remote caching for *builds* we should tag these type of outputs. `pull-kubernetes-bazel-test` already has this enabled and dropped in execution time by 70-80%

**Special notes for your reviewer**: See https://github.com/kubernetes/test-infra/issues/6808 for details on the remote caching. This should not affect local builds.
