PV binding: send an event when there are no PVs to bind
This is similar to scheduler that says "no nodes available to schedule pods"
when it can't schedule a pod.

Prevent pv controller from forcefully overwrite provisioned volume name
**What this PR does / why we need it**:
This PR adds a fix to prevents the PV controller from forcefully overwriting the provisioned volume's name with the generated PV name. Instead, it overwrites the volume's name only when it is missing. This allows dynamic provisioner implementers to set the name of the volume to a value that they choose.
**Which issue this PR fixes**
This PR does not have an issue affiliated, but it will allow PR #38924 to properly implement dynamically provisioned volume in namespaces other than default.

Move post processing/backward compatibility of openapi out of generic package

kubeadm: Refactoring the apiconfig and addons phases
**What this PR does / why we need it**:
First commit: Fix the defaulting for AuthorizationMode - **Ready for review**
Second commit: Refactoring the apiconfig and addons phases in kubeadm - **work in progress, broken at the moment**
**Special notes for your reviewer**:
Please take a look at the first commit now. You can also see the direction I'm going with the addons and apiconfig phases.
For example, I'm using Go templates instead of creating native Go structs for kube-dns and kube-proxy now. The question is if I should do it for the RBAC rules as well, it might make sense there as well.
Converting the dns addon to a yaml spec makes it 100x easier to maintain when changes are made to the "upstream" DNS spec, and also more swappable. We could for instance have a configuration param for it for those who want a custom file, etc.
**Release note**:
```release-note
NONE

Add StatefulSets checks at Service level
Hi!
Please let me propose some very small e2e testsuite enhancement.
This PR removed a `TODO` about checking governing service at unit test level (which is hard) and adds this to e2e testsuite.
Thanks
Sebastian

Exports KUBE_TEMP for use in Vagrantfile
In #40147, the logic for setting `KUBE_TEMP` was refactored into `common.sh`. However, it was overlooked that `KUBE_TEMP` [needs to be exported for vagrant to work properly](https://github.com/kubernetes/kubernetes/pull/40147/files#diff-b19d3d93456020e2168c7f304f722969).
This PR restores the `export` so that `Vagrantfile` can use `ENV["KUBE_TEMP"]` properly.

dnsprovider: Add direct access to Route53 data

Use of these methods should be avoided, and adding methods to the
cross-provider interfaces should be preferred.

kubeadm: preflight check for incorrect FQDN
**What this PR does / why we need it**: There are a variety of system configuration errors (such as cloud-init bugs when deploying on AWS) which can cause hostname and uname -n to be wrong for a given host. This will cause kubeadm setup to fail in interesting and hard-to-figure-out ways (it doesn't fail until you start trying to set up DNS on the master, for example).
This PR adds a preflight check to test whether or not the server can reach itself using that name. This does not catch the case that the FQDN belongs to a different but valid server, but it would catch some of the cases.
**Which issue this PR fixes** : fixes https://github.com/kubernetes/kubeadm/issues/135

Add bootstrap cluster role for external pv provisioners
The set of permissions an external provisioner https://github.com/kubernetes/kubernetes/pull/30285 running as a pod will need. Technically in order to dynamically provision PVs one doesn't need to "update" PVCs or "watch" events but the controller https://github.com/kubernetes-incubator/nfs-provisioner/tree/master/controller we are recommending people use does those things to: set lock annotations on PVCs and watch `ProvisioningSucceeded`/`ProvisioningFailed` events.
Some external provisioners may need additional permissions, for example nfs-provisioner requires "get" access to Services and Endpoints when run "statefully." I think in that case we would recommend creating a new ClusterRole specific to that provisioner, using this as a base?
(This was to be a part of my redo/fix of the external e2e test https://github.com/kubernetes/kubernetes/pull/39545 but I'm submitting it as a separate PR for now due to some issues I had with running nfs-provisioner on gce.)
