Azure: Allow VNet to be in a separate Resource Group
**What this PR does / why we need it**:
This PR allows Kubernetes in an Azure context to use a VNet which is not in the same Resource Group as Kubernetes.
We need this because currently Azure Cloud Provider driver assumes that it should have a VNet for himself but if there is one thing that should be shared amongst Azure resources it's a VNet cause, well, things might want to talk to each other in a private network, don't you think ?
I guess this should we backported down to 1.6 branch.

Improve GC discovery sync performance
Improve GC discovery sync performance by only syncing when discovered
resource diffs are detected. Before, the GC worker pool was shut down
and monitors resynced unconditionally every sync period, leading to
significant processing delays causing test flakes where otherwise

Fix unused Secret export logic.
**What this PR does / why we need it**:
The strategy used for the secret store defined custom export logic, and
had accompanying unit tests. However the secret storage did not actually
wire this up by setting an ExportStrategy and thus the code was never
used in the real world.
This change fixes the missing assignment and adds testing at a higher
level to ensure any uses of the generic registry.Store that we expect to
have an ExportStrategy do, and no others.
Several other strategies in the RBAC package also appeared to have
unwired Export logic, however their implementations were all empty
leading me to believe that these are not considered exportable. The
empty methods have now been removed.

Alpha Dynamic Kubelet Configuration
Feature: https://github.com/kubernetes/features/issues/281
This proposal contains the alpha implementation of the Dynamic Kubelet Configuration feature proposed in ~#29459~ [community/contributors/design-proposals/dynamic-kubelet-configuration.md](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md).
Please note:
- ~The proposal doc is not yet up to date with this implementation, there are some subtle differences and some more significant ones. I will update the proposal doc to match by tomorrow afternoon.~
- ~This obviously needs more tests. I plan to write several O(soon). Since it's alpha and feature-gated, I'm decoupling this review from the review of the tests.~ I've beefed up the unit tests, though there is still plenty of testing to be done.
- ~I'm temporarily holding off on updating the generated docs, api specs, etc, for the sake of my reviewers 😄~ these files now live in a separate commit; the first commit is the one to review.
/cc @dchen1107 @vishh @bgrant0607 @thockin @derekwaynecarr
```release-note
Adds (alpha feature) the ability to dynamically configure Kubelets by enabling the DynamicKubeletConfig feature gate, posting a ConfigMap to the API server, and setting the spec.configSource field on Node objects. See the proposal at https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md for details.

Run mount in its own systemd scope.
Kubelet needs to run /bin/mount in its own cgroup.
- When kubelet runs as a systemd service, "systemctl restart kubelet" may kill all processes in the same cgroup and thus terminate fuse daemons that are needed for gluster and cephfs mounts.
- When kubelet runs in a docker container, restart of the container kills all fuse daemons started in the container.
Killing fuse daemons is bad, it basically unmounts volumes from running pods.
This patch runs mount via "systemd-run --scope /bin/mount ...", which makes sure that any fuse daemons are forked in its own systemd scope (= cgroup) and they will survive restart of kubelet's systemd service or docker container.
This helps with #34965
As a downside, each new fuse daemon will run in its own transient systemd service and systemctl output may be cluttered.

Copy annotations from StatefulSet to owned ControllerRevisions
**What this PR does / why we need it**:
This PR starts copying annotations from a `StatefulSet`'s metadata to the `ControllerRevision`s it owns. `DaemonSet` controller copies the annotations from a `DaemonSet`s metadata to the `ControllerRevision`s it owns. One of the annotation copied is `kubernetes.io/change-cause`, which is used in `DaemonSetHistoryViewer` to fill in the `CHANGE-CAUSE` column of revision history of a `DaemonSet`.
For consistency, the `StatefulSet` controller should do the same, i.e., copy annotations in a `StatefulSet`'s metadata to the `ControllerRevision`s it owns for consistency.

kubectl: deploy generators don't need to impl Generator iface
The `kubectl create deployment` generators do not need to implement the Generator interface, since they are only used as implementations of the StructuredGenerator interface. I was able to delete some tests of their Generator methods as part of this change.
### Considerations for code reviewers
1. Every other StructuredGenerator implementation implements the Generator interface in additional. My change makes the "create deployment" generators a little unusual. I've added a docstring to this effect in `util/factory_client_access.go`.
2. This significantly reduces the maintenance / testing burden for future updates to `kubectl create deployment`.

Deprecate Deployment .spec.rollbackTo field

1. Deprecate Deployment field `.spec.rollbackTo` in `extensions/v1beta1` and `apps/v1beta1`, and remove the same field and `/rollback` endpoint from `apps/v1beta2` Deployment.
1. Add an annotation `deprecated.deployment.rollback.to` in `apps/v1beta2` for conversion to/from other versions.
Note: `apps/v1beta2` is new in 1.8 (and WIP), so it is okay to make breaking changes to it.
