Disable session affinity for internal kuberntes service
Under following conditions session affinity leads to a deadlock:
- Self hosted controller-manager, where it talks to API servers
via kubernetes service ClusterIP
- default master-count reconcilier is used
- --apiserver-count is set to >1 according to the help message
- number of responsive APIServers goes below `apiserver-count`
- all controller-managers happen to be hashed to APIServers which
are down.
What then happens is that controller managers never be able to
contact APIServer, despite correctly working APIServer available.
Less serious outages also possible for other consumers of kubernetes
service, such as operators, kube-dns, flannel & calico, etc. There is
always non zero chance, that given consumer is hashed to an apiserver
which is down.

Re-enable lease reconciler, fix shutdown race
Fixes#63378Fixes#57617
* Fixes the openapi script to wait for the apiserver on shutdown (like all the other scripts do)
* Fixes the apiserver shutdown to not hang forever if the kubernetes service reconciler cannot persist to etcd
* Readds https://github.com/kubernetes/kubernetes/pull/58474 to make the default the lease reconciler
```release-note
kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13.

stop duplicating preferred version order
`GroupMeta` includes two fields for a preferred groupVersion, `.GroupVersion` and `.GroupVersion[0]`. This collapses onto the latter.
@kubernetes/sig-api-machinery-pr-reviews
lots of ripples, but eliminate of duplication is good.

Expose default service IP CIDR in apiserver
**What this PR does / why we need it**:
The `--service-cluster-ip-range` parameter of API server is very important for deploying Kubernetes on some clouds. The default CIDR "10.0.0.0/24" should be exposed at least from the API server's help message so that users have a better idea whether they need to change it.
This patch exposes this default value in API server's help message.

Extend timeout to deal with pkg/master flake.
**What this PR does / why we need it**:
Workaround for bug #59450.
Related to PR #59441.
Locally test runs about 90 seconds.
However on the bazel-test CI the test frequently runs over 5 minutes.
Extending the timeout as a work-around to ease the rerun problem.
As @mikedanese notes :-
The Validate calls to the vendored go-openapi library are which make the test slow:
https://github.com/kubernetes/kubernetes/blob/master/pkg/master/master_openapi_test.go#L91
We should probably do more perf and send a patch to upstream.
**Special notes for your reviewer**:
This is intended as a work-around to unblock other PRs while someone investigates the timeout issue.
**Release note**:
```release-note
NONE

controller-manager: switch to options+config pattern and add https+auth
This PR switch the {kube,cloud}-controller-managers to use the Options+Config struct pattern for bootstrapping, as we use it throughout all apiservers. This allows us to easily plug in https and authn/z support.
Fixes parts of https://github.com/kubernetes/kubernetes/issues/59483
This is equivalent to https://github.com/kubernetes/kubernetes/pull/59408 after squashing.
```release-note
Deprecate insecure HTTP port of kube-controller-manager and cloud-controller-manager. Use `--secure-port` and `--bind-address` instead.
```

Add context to all relevant cloud APIs
**What this PR does / why we need it**:
This adds context to all the relevant cloud provider interface signatures.
Callers of those APIs are currently satisfied using context.TODO().
There will be follow on PRs to push the context through the stack.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#815
**Special notes for your reviewer**:
For an idea of the full scope of this change please look at PR #58532.
**Release note**:
```release-note
Implementers of the cloud provider interface will note the addition of a context to this interface. Trivial code modification will be necessary for a cloud provider to continue to compile.
```
TestValidOpenAPISpec often takes over a minute. This bumps the timeout
from 60 seconds to 300 seconds. On my computer it takes ~73 seconds
consisently. The calls to Validate() take the majority of the time.

Send events on certain service repair controller errors
**What this PR does / why we need it**:
This PR enables sending events when the api-server service IP and port allocator repair controllers find an error repairing a cluster ip or a port respectively.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54303
**Special notes for your reviewer**:
In case of an error, events will be emitted [every 3 minutes](https://github.com/kubernetes/kubernetes/blob/master/pkg/master/controller.go#L93) for each failed Service. Even so, event spam protection has been merged (#47367) to mitigate the risk of excessive events.
**Release note**:
```release-note
api-server provides specific events when unable to repair a service cluster ip or node port
```
