remove call to compinit in zsh completion output

**Release note**:
```release-note
release-note-none
```

Fixes: https://github.com/kubernetes/kubernetes/issues/32029
Fixes:
https://github.com/kubernetes/kubernetes/issues/27538#issuecomment-238574035

The zsh completion output makes a call to "compinit" which causes the
zsh completion system to re-initialize every time `<root_cmd> completion zsh`
is sourced, overwriting any settings already applied to other commands.
This in-turn caused other commands' completions to break (such as git,
gcloud, vim) causing an error "function definition file not found" to
be returned any time a tab-completion was attempted.

This patch removes the call to `compinit` in the zsh completion output,
causing no behavioral changes to the existing `completion` command, but
fixing any issues that were caused after sourcing its output.

kubeadm implement preflight checks

Checks that user running kubeamd init and join is root and will only execute
command if user is root. Moved away from using kubectl error handling to
having kubeadm handle its own errors. This should allow kubeadm to have
more meaningful errors, exit codes, and logging for specific kubeadm use
cases.

add flag for enabling RBAC on local-up-cluster

Enables cases like `ALLOW_ANY_TOKEN=true ENABLE_RBAC=true hack/local-up-cluster.sh ` to startup an api server so you can test RBAC against it.

@pweil- You can try this using `oc login localhost:6443 --token=username/group1,group2,system:masters`.  Then you should have full rights.  You can use `oc login --token=username` or `kubectl create -f - --token=otheruser/othergroup` to simulate other users.

Change legacy API resource registration

Updates the legacy API resource registration to emphasize its different-ness and to simplify supporting objects.  The option has to remain in the genericapiserverconfig for multiple prefixes to enable cases where composers/extenders had composed additional groupless APIs. See OpenShift as an example.

However this is now transparent to "normal" composers.

Update `gcloud docker` commands to use `gcloud docker -- ARGS`

We can then avoid the following warning:
```
WARNING: The '--' argument must be specified between gcloud specific args on the left and DOCKER_ARGS on the right. IMPORTANT: previously, commands allowed the omission of the --, and unparsed arguments were treated as implementation args. This usage is being deprecated and will be removed in March 2017.
This will be strictly enforced in March 2017. Use 'gcloud beta docker' to see new behavior.

kube-dns: Add --dns-bind-address flag

Currently, `kube-dns` always binds to `0.0.0.0` when starting the SkyDNS server. Sometimes it's useful to have it bind to a different address for testing. So add a new `--dns-bind-address` flag that can be used to configure this (default is `0.0.0.0`).

Includes checks for verifying services exist and are enabled, ports are
open, directories do not exist or are empty, and required binaries are
in the path.
