OpenShift runs Heapster on HTTPS, which means `top node` and `top pod`
are broken because they hardcode 'http' as the scheme. Provide an
options struct allowing users to specify `--heapster-namespace`,
`--heapster-service`, `--heapster-scheme`, and `--heapster-port` to the
commands (leveraging the existing defaults).

build: clean platform envs to prevent cross-contamination
**What this PR does / why we need it**: As I described in https://github.com/kubernetes/kubernetes/issues/37079#issuecomment-263733509, we are leaking platform compilation envs between build stages for different platforms in the non-parallel dockerized cross build. This PR uses a subshell for the non-parallel build, more closely matching the parallel build.
This also adds some logging, which had it existed previously, may have made the bug more immediately obvious.
**Which issue this PR fixes**: fixes#37079

hack/e2e.go: Dump cluster logs in case of Up failure
**What this PR does / why we need it**: A failure in `Up` currently results in no attempt to grab cluster logs. This fixes that hole. (Sigh, a ton of holes for this diagnosis path.)

move parts of the mega generic run struct out
This splits the main `ServerRunOptions` into composeable pieces that are bindable separately and adds easy paths for composing servers to run delegating authentication and authorization.
@sttts @ncdc alright, I think this is as far as I need to go to make the composing servers reasonable to write. I'll try leaving it here

Fix package aliases to follow golang convention
Some package aliases are not not align with golang convention https://blog.golang.org/package-names. This PR fixes them. Also adds a verify script and presubmit checks.

When --grace-period=0 is provided, wait for deletion
The grace-period is automatically set to 1 unless --force is provided, and the client waits until the object is deleted.
This preserves backwards compatibility with 1.4 and earlier. It does not handle scenarios where the object is deleted and a new object is created with the same name because we don't have the initial object loaded (and that's a larger change for 1.5).
Fixes#37117 by relaxing the guarantees provided.
```release-note
When deleting an object with `--grace-period=0`, the client will begin a graceful deletion and wait until the resource is fully deleted. To force deletion, use the `--force` flag.

Node Conformance Test: Final cleanup for node conformance test.
This PR fits node conformance test with recent change.
* Remove `--manifest-path` because the test will get kubelet configuration through `/configz` now. https://github.com/kubernetes/kubernetes/pull/36919
* Add `$TEST_ARGS` so that we can override arguments inside the container.
* Fix a bug in garbage_collector_test.go which will cause the framework tries to connect docker no matter running the test or not. @dashpole
* Add `${REGISTRY}/node-test:${VERSION}` for convenience.
* Bump up the image version to `0.2`. (the one released with v1.4 is `v0.1`)
I've run the test both with `run_test.sh` script and directly `docker run`. Both of them passed.
After this gets merged, I'll build and push the new test image.

add wrapper to provide stderr on command errors
The go standard library doesn't include stderr in the error message, but in many cases it is present: https://golang.org/src/os/exec/exec.go#L389 . This adds a wrapper to display that information. I've added in it on spot where the kops test is having trouble. If it works well, we can add it elsewhere.

Node E2E: Fix remote node e2e focus.
Before, we use `'focus'` and `'skip'` in `hack/make-rules/test-e2e-node.sh`.
When we run `make test-e2e-node REMOTE=true FOCUS="Some Thing"`, it will eventually be translated to `-focus='Some Thing'` [here](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/remote/remote.go#L284-L285).
However, golang `exec.Command` wraps each argument with single quote, the argument will become `'xx -focus='Some Thing' xx'`, and cause error because of the 2 layer single quote.

Removes shorthand flag -w from kubectl apply
Fixes#37342.
A shorthand flag `-w` was introduced as flag `--prune-whitelist` for kubectl apply two weeks ago. Turned out it is not what we should do. Removing this shorthand flag before 1.5 release to prevent further issues.

Fixed e2e tests for HA master.
Set of fixes that allows HA master e2e tests to pass for removal/addition master replicas.
The summary of changes:
- fixed host name in etcd certs,
- added cluster validation after kube-down,
- fixed the number of master replicas in cluster validation,
- made MULTIZONE=true required for HA master deployments, ensured we correctly handle MULTIZONE=true when user wants to create HA master but not kubelets in multiple zones,
- extended verification of master replicas in HA master e2e tests.
- Fix unbound variables in hack/local-up-cluster.sh
- explicitly set KUBERNETES_PROVIDER in local-up-cluster.
The default appears to be gce now, so this tries to spawn a service
in gce... not the desired outcome for a local test setup.
- Remove stale creation of kube-system: the kube-system namespace is
built in these days.
- Pickup third party etcd automatically.
- Retab hack/local-up-cluster.sh for consistency
- Update hack-local-up's internal credentials to match the user
instructions we give (which work).
- Note the CA root requirement in local-up-cluster
- Fix a dangling comment in local-up-cluster
To test manually, run something like:
```sudo KUBE_ENABLE_CLUSTER_DNS+true API_HOST_IP=0.0.0.0
./hack/local-up-cluster.sh```
The API_HOST_IP=0.0.0.0 is required otherwise kubedns cannot contact
the master and the dns pod will fail readychecking on the healthz
container.

[Federation][join-flags] Add flags for cluster context and secret names while joining clusters to federation.
Vast majority of cluster contexts are not RFC 1123 subdomains. Since
cluster and secret names for the API objects are derived from the
cluster context name, there is no way for users to join clusters
with such context names to federation, unless they modify the context
name in their kubeconfigs itself. That's a lot of inconvenience and
entirely goes against the goal and beats the purpose of the `kubefed`
tool. So we are providing these flags to allow users to override these
values.
Also, since users register their clusters with federation, it is makes
sense in terms of user experience to make the cluster name a positional
argument because that feels more natural. Also, specifying cluster name
in the join command as a mandatory positional argument make
`kubefed join` consistent with `kubefed unjoin`. This also means
`--cluster-context` is now made a flag and defaults to cluster name if
unspecified.
`--secret-name` also defaults to the cluster name if unspecified.
