Sort resources in quota errors to avoid duplicate events
Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1333122
Errors describing why a request was rejected to quota would get variable responses (cpu=x,memory=y or memory=x,cpu=y) which caused duplicate events for the same root cause.

Display line number on JSON errors
Related issue: https://github.com/kubernetes/kubernetes/issues/12231
This PR will introduce line numbers for all JSON errors in the CLI:
(this is existing error reporting for YAML)
```console
$ kubectl create -f broken.yaml
yaml: line 8: mapping values are not allowed in this context
```
(this is error reporting proposed in this PR for JSON)
```console
$ kubectl create -f broken.json
json: line 35: invalid character '{' after object key
```
(and this is the current reporting:)
```console
$ kubectl create -f broken.json
invalid character '{' after object key
```

GCI/Trusty: Fix the running of kube-addon-manager
This PR fixes the issue that kube-addon-master (added in #23600) is not started. Without this fix, no kube-system pods can be running correctly. As a result, the GCI-based Jenkins testing k8s head has been down for a couple of days. The root cause is that we stopped to use namespace.yaml, but configure-helper.sh still tries to copy it. This PR also gets rid of /var/cache/kubernetes-install/kube_env.yaml, as it is not needed anymore after #24108.
@mikedanese @roberthbailey @dchen1107 please review it. If possible please mark it as P1, as it blocks GCI-based Jenkins tests.

Added vsphere support for vagrant
Since the native vsphere support (using govc library) requires admin permissions on ESX/vCenter, not everyone can have such permissions. So I'm adding a vsphere support using vagrant using vagrant-vsphere plugin

GCE: Allow node count to exceed GCE TargetPool maximums
```release-note
If the cluster node count exceeds the GCE TargetPool maximum (currently 1000),
randomly select which nodes are members of Kubernetes External Load Balancers.
```
[]()
If we would exceeded the TargetPool API maximums, instead just
randomly select some subsection of the nodes to include in the TP
instead.

etcd3/watcher: fix goroutine leak if ctx is canceled
### Problem
In reflector.go, it could probably call Stop() without retrieving all results
from ResultChan(). See [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/client/cache/reflector.go#L369). A potential leak is that when an error has happened, it could block on resultChan,
and then cancelling context in Stop() wouldn't unblock it.
### What's this PR?
This fixes the problem by making it also select ctx.Done and cancel context afterwards if error happened.

create command guidance
`kubectl create <resource>` commands are multiplying (configmap, namespace, secret (2 flavors and a pull for a third), and serviceaccounts so far) and I think we should agree on the goal of those subcommands.
Right now, `kubectl run` is an easy entrypoint for new users or users who don't really care which resources are created. It is possible to get stable output from `kubectl run`, but it really is intent-based: make this image go in some reasonable way. At the other end of the spectrum, you can craft yaml files by hand get exactly the object you want, but that requires pretty deep API knowledge. I think that `kubectl create <resource>` should be the starting point of the middle ground.
`kubectl create <resource>` commands should have just enough arguments to create valid objects and the expectation should be that users will use those objects as skeletons to tweak using `kubectl edit` or the future `kubectl set` to modify them after the fact. Editing an already existing and valid object is a lot easier than creating one from scratch, so it reduces the barrier to entry.

Add data structure for managing go routines by name
This PR introduces a data structure for managing go routines by name. It prevents the creation of new go routines if an existing go routine with the same name exists. This will enable parallelization of the designs in https://github.com/kubernetes/kubernetes/issues/20262 and https://github.com/kubernetes/kubernetes/issues/21931 with sufficient protection to prevent starting multiple operations on the same volume.

enable resource name and service account cases for impersonation
Adds the resource name check since that attribute was added for authorization. Also adds a check against a separate resource for service accounts. Allowing impersonation of service accounts to use a different resource check places control of impersonation with the same users to have the power to get the SA tokens directly.

Kubelet eviction flag parsers and tests
The first two commits are from https://github.com/kubernetes/kubernetes/pull/24559 that have achieved LGTM.
The last commit is only part that is interesting, it adds the parsing logic to handle the flags, and reserves `pkg/kubelet/eviction` for eviction manager logic.

test/e2e/addon_update: Respect KUBE_SSH_USER
This change makes the e2e tests more consistent as the other ones all already respected this variable.
I didn't do the larger change of re-factoring it to use `framework.SSH` because getting the `scp` portion working there has some significant complexity. If I find time, I'd like to go back and do it since this test needs a little ❤️
