Uncordon the node after upgrade
**What this PR does / why we need it**:
Previous logic was relying on the node to recreate the node API object
and, as a side-effect, uncordon itself. A change went in that no
longer ensures the node recreates itself, so the bug in this logic was exposed.

Optimize admission plugin API requests
xref https://github.com/kubernetes/kubernetes/issues/63030#issuecomment-387774934
* resource changes are typically slow-moving, and full discovery can be slightly expensive, so this reduces the refresh to a 30 second interval and bumps QPS on the admission client (which wasn't done when the client started getting used for discovery in #62659)
* a large consumer of API requests in scale tests was the node restriction plugin pod lookups during pod deletion. this switches to use the same informer that is feeding the node authorizer graph to avoid those lookups entirely.

Remove 20x factor in garbage-collector qps
Fixes https://github.com/kubernetes/kubernetes/issues/63610
I was discussing offline with @wojtek-t. And among the two options of:
- Increasing the qps 20x to compensate for the earlier "bloated" qps (this kind of assumes that we have ~20 resource types in the cluster)
- Keeping the qps same to make sure that we don't overwhelm the apiserver with the new re-adjusted qps (like what seems to happen with our performance tests where we mostly just have ~1 resource type)
we agreed that the latter one seems to be less riskier as it's probably better to have the GC slower than to make our API call latencies shoot up.
That said, we can try to increase it later if it's justifiable.
cc @kubernetes/sig-api-machinery-misc @deads2k @wojtek-t
```release-note
GC is now bound by QPS (it wasn't before) and so if you need more QPS to avoid ratelimiting GC, you'll have to set it.

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.

change deprecated Kubelet --allow-privileged flag default to true
This enables a smooth transition to PSP. Today, users would have to
manually set --allow-privileged to true before transitioning to PSP,
which isn't a smooth deprecation path for the flag (we want people
to *stop* setting it). This PR makes the default behavior isomorphic
with what will happen after the flag is removed.
Defaulting --allow-privileged to true should be safe, because it simply
allows a superset of Pods to run (all workloads continue to work).
WRT https://github.com/kubernetes/kubernetes/issues/58010#issuecomment-383264473
the --allow-privileged flag is effectively useless for security, so this
shouldn't be a concern from that perspective.
I also bumped the deprecation timeline in the comment to 1.13.0, so that
we give people the full period of time to stop setting
--allow-privileged, now that the behavior makes it possible to do so.
```release-note
The Kubelet's deprecated --allow-privileged flag now defaults to true. This enables users to stop setting --allow-privileged in order to transition to PodSecurityPolicy. Previously, users had to continue setting --allow-privileged, because the default was false.

explicit kubelet config key in Node.Spec.ConfigSource.ConfigMap
This makes the Kubelet config key in the ConfigMap an explicit part of
the API, so we can stop using magic key names.
As part of this change, we are retiring ConfigMapRef for ConfigMap.
```release-note
You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file.
