Added validation for API server's 'apiserver-count' flag.
Added validation for API server's 'apiserver-count' flag. The value of this flag should be a positive number, otherwise, will cause error while reconciling endpoints in MasterCountEndpointsReconciler.

move name generation to generic api server storage helpers
Move name generation to the genericapiserver since only the server needs to know about it.

kubeadm: must lower-case token portion used in DNS label.
**What this PR does / why we need it**: In Kubernetes, DNS labels must be lower-case. `kubeadm` doesn't care when creating certain objects through the API. This PR fixes that erroneous behavior.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubeadm/issues/104

move api/errors to apimachinery
`pkg/api/errors` is a set of helpers around `meta/v1.Status` that help to create and interpret various apiserver errors. Things like `.NewNotFound` and `IsNotFound` pairings. This pull moves it into apimachinery for use by the clients and servers.
@smarterclayton @lavalamp First commit is the move plus minor fitting. Second commit is straight replace and generation.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the future in
the **reviewers** section. You probably do NOT need to modify the **approvers**
section. Names asre sorted by relevance, using some secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

add --controllers to controller manager
Adds a `--controllers` flag to the `kube-controller-manager` to indicate which controllers are enabled and disabled. From the help:
```
--controllers stringSlice A list of controllers to enable. '*' enables all on-by-default controllers, 'foo' enables the controller named 'foo', '-foo' disables the controller named 'foo'.
All controllers: certificatesigningrequests, cronjob, daemonset, deployment, disruption, endpoint, garbagecollector, horizontalpodautoscaling, job, namespace, podgc, replicaset, replicationcontroller, resourcequota, serviceaccount, statefuleset

**Special notes for your reviewer**: It was tested manually by bootstrapping a new cluster, running a busybox container and making sure one could `nslookup` from within the container to find `kubernetes` and other services.
