Add a package for handling version numbers (including non-"Semantic" versions)
As noted in #32401, we are using Semantic Version-parsing libraries to parse version numbers that aren't necessarily "Semantic". Although, contrary to what I'd said there, it turns out that this wasn't actually currently a problem for the iptables code, because the regexp used to extract the version number out of the "iptables --version" output only pulled out three components, so given "iptables v1.4.19.1", it would have extracted just "1.4.19". Still, it could be a problem if they later release "1.5" rather than "1.5.0", or if we eventually need to _compare_ against a 4-digit version number.
Also, as noted in #23854, we were also using two different semver libraries in different parts of the code (plus a wrapper around one of them in pkg/version).
This PR adds pkg/util/version, with code to parse and compare both semver and non-semver version strings, and then updates kubernetes to use it everywhere (including getting rid of a bunch of code duplication in kubelet by making utilversion.Version implement the kubecontainer.Version interface directly).
Ironically, this does not actually allow us to get rid of either of the vendored semver libraries, because we still have other dependencies that depend on each of them. (cadvisor uses blang/semver and etcd uses coreos/go-semver)

Add an option to run Job in Density/Load config
cc @timothysc @jeremyeder
@erictune @soltysh - I run this test and it seems to me that Job has noticeably worse performance than Deployment. I'll create an issue for this, but this PR is for easy repro.

Fix running e2e with 'Completed' kube-system pods
As of now, e2e runner keeps waiting for pods in `kube-system` namespace to be "Running and Ready" if there are any pods in `Completed` state in that namespace.
This for example happens after following [Kubernetes Hosted Installation](http://docs.projectcalico.org/v2.0/getting-started/kubernetes/installation/#kubernetes-hosted-installation) instructions for Calico, making it impossible to run conformance tests against the cluster. It's also to possible to reproduce the problem like that:
```
$ cat testjob.yaml
apiVersion: batch/v1
kind: Job
metadata:
name: tst
namespace: kube-system
spec:
template:
metadata:
name: tst
spec:
containers:
- name: tst
image: busybox
command: ["echo", "test"]
restartPolicy: Never
$ kubectl create -f testjob.yaml
$ go run hack/e2e.go -v --test --test_args='--ginkgo.focus=existing\s+RC'

Delete regional static-ip instead of global for type=lb
Global vs region is the difference between
```
$ gcloud compute addresses delete foo --global
$ gcloud compute addresses delete foo --region us-central1
```
Type=LoadBalancer users the second type and were were doing the first.
Also adds some logging.

test: wait for ready replica set before adopting
Reworked version of https://github.com/kubernetes/kubernetes/pull/36439 which was reverted in https://github.com/kubernetes/kubernetes/pull/38049. This PR doesn't use any of the new status API added in replica sets so it should cause no trouble with upgrade tests.

Fixes flake: wait for dns pods terminating after test completed
From #37194. Based on #36600. Please only look at the second commit.
As mentioned in [comment](https://github.com/kubernetes/kubernetes/issues/37194#issuecomment-262007174), "DNS horizontal autoscaling" test does not wait for the additional pods to be terminated and this may lead to the failure of later tests.
This fix adds a wait loop at the end of the serial test to ensure the cluster recovers to the original state. In the non-serial test it does not wait for the additional pods terminating because it will not affect other tests, given they are able to be run simultaneously. Plus wait for pods terminating will take certain amount of time.
Note this only fixes certain case of #37194. I noticed there are other failures irrelevant to dns autoscaler. LIke [this one](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gce-serial/34/).

test: update deployment helper to return better error messages
@kubernetes/deployment the problem with https://github.com/kubernetes/kubernetes/issues/36270 is that the selector key is never added in the deployment but this change would make it clearer.

Moved gobindata, refactored ReadOrDie refs

test: update rollover test to wait for available rs before adopting
Scenario that happened in https://github.com/kubernetes/kubernetes/issues/35355#issuecomment-257808460
-- Replica set that is about to be adopted has 2 out of 4 ready replicas
-- Deployment is created with 4 replicas, adopts pre-existing replica set, creates a new one, and starts rolling replicas over to the new replica set.
```

```
At this point there is no minimum availability for the Deployment (maxUnavailable is 1 meaning desired minimum available is 3 but we only have 2), and the new replica set uses a non-existent image. New replica set is scaled up to 1 (maxSurge is 1), then old replica set is scaled down by one, because cleanupUnhealthyReplicas observes that it has 2 unhealthy replicas - it can only scale down one though because the [maximum replicas it can cleanup is one](d87dfa2723/pkg/controller/deployment/rolling.go (L125)) (4+1-3-1). New replica set is scaled to 2. Available replicas are still 2 (third replica from the old replica set has yet to come up).
-- Deployment is rolled over with a new update. Test reaches for the WaitForDeploymentStatus check but there are only 2 availableReplicas (maxUnavailable is still violated).
This change makes the test wait for a healthy replica set before proceeding thus it should never hit the scenario described above.

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.
Fixes#35070.

Checking the result.Code prior to err in the if statement causes a panic
if result is nil. It turns out the formatting of the error is already in
IssueSSHCommandWithResult, so removing redundant code is enough to fix
the issue. Logging the SSH result was also redundant, so I removed that
as well.
This disables ready replica checking for 1.3 masters, but only from 1.4
or 1.5 clients. The old logic was broken anyway due to overlapping
labels with replica sets.
