Control exactly what we use in kubeadm

we recently got rid of extra arg validation for preflight check:

the import-boss configuration will help us control exactly what
gets added/used in kubeadm. In this PR, we add a white-list of

register client-go auth plugins for e2e

e2e depends on use of the gcp client-go auth provider, but did not explicitly register the auth provider. it indirectly imported the plugins via a roundabout chain (see https://github.com/kubernetes/kubernetes/issues/63731#issuecomment-388529120) which broke when those imports were trimmed in https://github.com/kubernetes/kubernetes/pull/63673

if e2e requires these auth plugins, it should include them explicitly in the top-level test package

 kubeadm: add test coverage to completion.go

**What this PR does / why we need it**:
Add `completion_test.go` with the following tests:
- TestNewCmdCompletion
- TestRunCompletion

A separate commit exports the function GetSupportedShells() to obtain the list of supported shells.

Test coverage is at 96%. The only untested bit is an `io.Writer.Write()` call in `RunCompletion()`. in the case of `bytes.Buffer` it would panic and/or always return `nil` for `error`.

Report node DNS info with --node-ip

**What this PR does / why we need it**:
This PR adds `ExternalDNS`, `InternalDNS`, and `ExternalIP` info for kubelets with the `--nodeip` flag enabled. 

**Which issue(s) this PR fixes** 
Fixes #63158

**Special notes for your reviewer**:

I added a field to the Kubelet to make IP validation more testable (`validateNodeIP` relies on the `net` package and the IP address of the host that is executing the test.) I also converted the test to use a table so new cases could be added more easily.

**Release Notes**
```release-note
Report node DNS info with --node-ip flag

e2e: add a tooling argument to differentiate tooling

We expect lots of tools to be able to install on provider=gce - the cluster
API, kops, kube-up etc.

We introduce a new optional flag to e2e ('tooling') to enable switching on
the tooling, not just the cloud.

This will prove useful for upgrade tests, for example, where the mechanism
will likely vary by tooling, but is currently tightly bound to the provider
(i.e. cloud)

Add instructions on how to debug a crashed pod

When I was using `kubeadm init`, I ran into an issue where I had passed an
invalid flag through the kubeadm config file. The flag was being passed into
apiserver and preventing it from launching with a "unknown flag" error.

The flag in question is (other flags elided for clarity):

```
admission-control: ...,GenericAdmissionWebhook,...
```

Since this prevented the apiserver from coming up, the setup timed out
and gave me the error message I just modified.

It would be better if the config was vetted more thoroughly, but I think
documenting the backup strategy for viewing logs in case of failure is
also valuable.

re-enable nodeipam in kube-controller-manager

**What this PR does / why we need it**:
Re-enables nodeipam controller for external clouds. Also does a small refactor so that we don't need to pass in `allocateNodeCidr` into the controller. 

In v1.10 we made a change (https://github.com/kubernetes/kubernetes/commit/9187b343e17db2bf8f3470cd6e1ef7f661814c15#diff-f11913dc67d80d36b3d06a93f61c49cf in https://github.com/kubernetes/kubernetes/pull/57492) where nodeipam would be disabled for any cluster that sets `--cloud-provider=external`. The original intention behind this was that the nodeipam controller is cloud specific for some clouds (only GCE at the moment) so it should be moved to the CCM (cloud controller manager). After some discussions with wg-cloud-provider it makes sense to re-enable nodeipam controller in KCM and have GCE CCM enable its own cloud-specific IPAM controller as part of [Initialize()](https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/cloud.go#L33-L35). This would allow for GCE to run nodeipam in both KCM (by setting --cloud-provider=gce and --allocate-node-cidr) and in the CCM (once implemented in `Initialize()`) without disabling nodeipam in the KCM for all external clouds and avoids having to implement nodeipam in CCM.

kubeadm - add preflight warning when using systemd-resolved

**What this PR does / why we need it**:

This PR adds a preflight warning when the host is running systemd-resolved.

Newer Ubuntu releases (artful and bionic in particular) run systemd-resolved by default and in the dfeault configuration have an /etc/resolv.conf file that references 127.0.0.53 which is not accessible from containers running on the host. We will now provide a warning to the user to tell them that the kubelet args should include `--resolv-conf=/run/systemd/resolve/resolv.conf`. `/run/systemd/resolve/resolv.conf`. 

**Which issue(s) this PR fixes**:
This does not resolve the following issues, but it does provide better output to the users affected by the issues: https://github.com/kubernetes/kubeadm/issues/273 https://github.com/kubernetes/kubeadm/issues/787
