add defaultTolerationSeconds admission controller
**What this PR does / why we need it**:
Splited from #34825, add a new admission-controller that
1. adds toleration (with tolerationSeconds = 300) for taint `notReady:NoExecute` to every pod that does not already have a toleration for that taint, and
2. adds toleration (with tolerationSeconds = 300) for taint `unreachable:NoExecute` to every pod that does not already have a toleration for that taint.

Related issue: #1574

kubeadm: Make a separate util package for kubeconfig logic
**What this PR does / why we need it**:
There are a lot of packages that need to consume kubeconfig logic, so it should be in a central place.
Having it in `kubeadmutil` is suboptimal, because then it get mixed with everything else.
This splits that logic out to a generic place so it then also can be consumed in https://github.com/kubernetes/kubernetes/pull/41417, from where it's broken out.
- Move {admin,kubelet}.conf out as constants
- Make a separate util package for kubeconfig logic
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

Allow `make test` to pass on OSX
**What this PR does / why we need it**: `make test` doesn't pass on my OSX setup (10.11.6, go1.7, docker 1.13.1) on `master`, `release-1.5`, nor `release-1.4`. Our [docs on unit tests](https://github.com/kubernetes/community/blob/master/contributors/devel/testing.md#unit-tests) say they should always pass on OS X. This PR allows them to pass.

Added a basic monitor for providing etcd version related info
Fixes#41071
This tool scrapes metrics partly from etcd's /version and /metrics endpoints and partly using etcdctl and exposes them as prometheus metrics at `http://localhost:9101/metrics` endpoint on the master. Here is a summary of the metrics it exposes (self-explanatory from the code):
- etcdVersionFetchCount = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: "etcd",
Name: "version_info_fetch_count",
Help: "Number of times etcd's version info was fetched, labeled by etcd's server binary and cluster version",
},
[]string{"serverversion", "clusterversion"})
- etcdGRPCRequestsTotal = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: namespace,
Name: "grpc_requests_total",
Help: "Counter of received grpc requests, labeled by grpc method and grpc service names",
},
[]string{"grpc_method", "grpc_service"})
For further info on how to run this as a binary/docker-container/kubernetes-pod and checking the metrics, have a look at the README.md file.

Adds functionality to look at the components of the GOPATH looking for
the gazel executable, rather than treating the GOPATH as if it was a

Make fuzzing tests as simple as possible from both the API installer and the scheme, so its easy to add for api groups and so that I can build a scheme and then make sure I got it right.

**What this PR does / why we need it**: the shortcut expander will take the list of short names for resources from the API server during the discovery. For backward compatibility a hardcoded list of short names will always be appended while evaluating a short name.

make kube-aggregator run as static pod for local-up-cluster
Runs the kube-aggregator as a static pod for local-up-cluster. Looks like someone broke kubectl negotiation again, so I'll fix that up separately.
@kubernetes/sig-api-machinery-misc
@lavalamp you're probably looking to run kube-aggregator as a static pod, here's an example.
@jwforres I'll make a secure variant for wiring up to openshift.

cluster/gce: Add env var to enable apiserver basic audit log.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly
to /var/log/kube-apiserver.log. Allowing other customization would
require significantly more complex changes.
Audit log rotation is handled the same as for `kube-apiserver.log`.
**What this PR does / why we need it**:
Add a knob to enable [basic audit logging](https://kubernetes.io/docs/admin/audit/) in GCE.
**Which issue this PR fixes**:
**Special notes for your reviewer**:
We would like to cherrypick/port this to release-1.5 also.
**Release note**:
```release-note
The kube-apiserver [basic audit log](https://kubernetes.io/docs/admin/audit/) can be enabled in GCE by exporting the environment variable `ENABLE_APISERVER_BASIC_AUDIT=true` before running `cluster/kube-up.sh`. This will log to `/var/log/kube-apiserver-audit.log` and use the same `logrotate` settings as `/var/log/kube-apiserver.log`.

move kube-aggregator to staging
Straight move of kube-aggregator to staging. The scripts are the interesting bits.
@sttts @lavalamp
This change makes kubelet to use the CRI implementation by default,
unless the users opt out explicitly by using --enable-cri=false.
For the rkt integration, the --enable-cri flag will have no effect
since rktnetes does not use CRI.
Also, mark the original --experimental-cri flag hidden and deprecated,
so that we can remove it in the next release.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly
to /var/log/kube-apiserver.log. Allowing other customization would
require significantly more complex changes.
Audit log rotation is handled externally by the wildcard /var/log/*.log
already configured in configure-helper.sh.

Add verify-gofmt as a Bazel test.
Also, moved `--flaky_test_attempts=3` out of `.bazelrc` since it was annoying. I think this verify-all pattern is working well in test-infra, we should try and make it happen here.

copy pkg/util/logs to apiserver
This is a copy, not a move. API servers need to be able to init the logs, but so do clients. It would be weird to have the client-side commands depending on the server side logs utilities.
I updated all the server side references, but left the client-side ones.
@sttts @kubernetes/sig-api-machinery-pr-reviews acceptable?
