Refactor storage factory config with Complete().New() flow
**What this PR does / why we need it**:
1. Split `BuildStorageFactory` constructor into `Complete().New()` flow to build an instance for etcd storage.
2. Put `EtcdOptions` and `StorageSerializationOptions` into a `StorageFactoryOptions` for a more reasonable structured config object.

Explicitly disable dry run for connect
**What this PR does / why we need it**:
It isn't clear whether or not dry run would work on connect. I think we should explicitly disable it so no one can try to dry run a connect request and accidentally open a connection.
**Release note**:
```release-note
kube-apiserver: setting a `dryRun` query parameter on a CONNECT request will now cause the request to be rejected, consistent with behavior of other mutating API requests. Examples of CONNECT APIs are the `nodes/proxy`, `services/proxy`, `pods/proxy`, `pods/exec`, and `pods/attach` subresources. Note that this prevents sending a `dryRun` parameter to backends via `{nodes,services,pods}/proxy` subresources.

Support dry run in admission plugins
**What this PR does / why we need it**:
Adds support for dry run to admission controllers as outlined by https://github.com/kubernetes/community/pull/2387
- [x] add IsDryRun() to admission.Attributes interface
- [x] add dry run support to NamespaceAutoProvision
- [x] add dry run support to ResourceQuota
- [x] add dry run support to EventRateLimit
The following is being done in a follow up PR:
- [x] add DryRun to ```admission.k8s.io/v1beta1.AdmissionReview```
- [x] add DryRunnable to ```admissionregistration.k8s.io/v1beta1.(Valid|Mut)atingWebhookConfiguration```
- [x] add dry run support to (Valid|Mut)atingAdmissionWebhook
/sig api-machinery
**Release note**:
```release-note
In clusters where the DryRun feature is enabled, dry-run requests will go through the normal admission chain. Because of this, ImagePolicyWebhook authors should especially make sure that their webhooks do not rely on side effects.
```
Here is a list of the admission controllers that were considered when making this PR:
- AlwaysAdmit: No side effects
- AlwaysPullImages: No side effects
- LimitPodHardAntiAffinityTopology: No side effects
- DefaultTolerationSeconds: No side effects
- AlwaysDeny: No side effects
- EventRateLimit: Has side possible effect of affecting the rate, skipping this entire plugin in dry-run case since it won't correspond to an actual write to etcd anyway
- DenyEscalatingExec: No side effects
- DenyExecOnPrivileged: Deprecated, and has no side effects
- ExtendedResourceToleration: No side effects
- OwnerReferencesPermissionEnforcement: No side effects
- ImagePolicyWebhook: No side effects* (*this uses a webhook but it is very specialized. It only sees pod container images, for the purpose of accepting or rejecting certain image sources, so it is very unlikely that it would rely on side effects.)
- LimitRanger: No side effects
- NamespaceAutoProvision: Has possible side effect of creating a namespace, skipping the create in the dry-run case
- NamespaceExists: No side effects
- NodeRestriction: No side effects
- PodNodeSelector: No side effects
- PodPreset: No side effects
- PodTolerationRestriction: No side effects
- Priority: No side effects
- ResourceQuota: Has side possible effect of taking up quota, will only check quota but skip changing quota in the dry-run case
- PodSecurityPolicy: No side effects
- SecurityContextDeny: No side effects
- ServiceAccount: No side effects
- PersistentVolumeLabel: No side effects
- PersistentVolumeClaimResize: No side effects
- DefaultStorageClass: No side effects
- StorageObjectInUseProtection: No side effects
- Initializers: No side effects
- NamespaceLifecycle: No side effects
- MutatingAdmissionWebhook: Same as below
- ValidatingAdmissionWebhook: Has possible side effects depending on if webhook authors depend on side effects and a reconciliation mechanism. To fix this we will expose whether or not a request is dry-run to webhooks through AdmissionReview, and require that all called webhooks understand the field by checking if DryRunnable true is specified in the webhook config. This will be done in a separate PR because it requires an api-change

Makes kubectl wait exit with status 1 and print an error message, if there is no resources matching selectors
**What this PR does / why we need it**:
It makes the `kubectl wait` command print an error message and exit with exit code 1, if there is no resource matching users's query. This can happen when user specifies selectors. Example:
```
kubectl wait deployment -l app=something-that-does-not-exist --for condition=available --timeout=5s
```
**Which issue(s) this PR fixes**:
Fixes#66456
**Special notes for your reviewer**:
This is my first contribution into the project (except one line change in docs) and don't have much experience with Go. I learned a lot while working on this (about resource finders and the `Visitor` interface and it's implementations), but it is very likely that I'm doing something wrong :)
I'm keen to continue contributing into the project (into the cli part for now), so I will really appreciate detailed feedback, if you have a chance to provide it (point me into a right direction and/or explain why it's not a good idea to do something in a certain way).
Thanks!
**Release note**:
```release-note
kubectl: the wait command now prints an error message and exits with the code 1, if there is no resources matching selectors

Add availability zones support to Azure managed disks
**What this PR does / why we need it**:
Continue of [Azure Availability Zone feature](https://github.com/kubernetes/features/issues/586).
This PR adds availability zone support for Azure managed disks and its storage class. Zoned managed disks is enabled by default if there are zoned nodes in the cluster.
The zone could also be customized by `zone` or `zones` parameter, e.g.
```yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
annotations:
name: managed-disk-zone-1
parameters:
zone: "southeastasia-1"
# zones: "southeastasia-1,"southeastasia-2"
cachingmode: None
kind: Managed
storageaccounttype: Standard_LRS
provisioner: kubernetes.io/azure-disk
reclaimPolicy: Delete
volumeBindingMode: Immediate
```
All zoned AzureDisk PV will also be labeled with its availability zone, e.g.
```sh
$ kubectl get pvc pvc-azuredisk-az-1
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-azuredisk-az-1 Bound pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c 5Gi RWO managed-disk-zone-1 2h

ImagePullCheck outputs "pulling <image>" line even if image
already exists and is not pulled.

Rework multi-volume test to use StatefulSet
**What this PR does / why we need it**:
The e2e test that got added as part of https://github.com/kubernetes/kubernetes/pull/66832 fails in a multi-zone environment because the volumes get provisioned in random zones. This PR reworks the test to use StatefulSet instead, which handles provisioning multiple PVCs in the same zone.
