Remove optimization from getWork in resourcequota/controller.go
**What this PR does / why we need it**:
This change simplifies the code in
plugin/pkg/admission/resourcequota/controller.go by removing the
optimization in getWork that required the caller to NOT call
completeWork if getWork returns the empty list of work. BTW, the
caller was not obeying that requirement; now the caller's behavior
(which is unchanged) is right.

Short-circuit node authorizer graph edges for mirror pods
When building the graph of resources allowed to a node by a given pod, short-circuit adding edges to other resources for mirror pods. A node must never be able to create a pod that grants them permissions on other API objects. The NodeRestriction admission plugin prevents creation of such pods, but short-circuiting here gives us defense in depth.

Allow for listing & watching individual secrets from nodes
This PR:
- propagates value of `metadata.name` field from fieldSelector to `name` field in RequestInfo (for list and watch requests)
- authorizes list/watch for requests for single secrets/configmaps coming from nodes
As an example:
```
/api/v1/secrets/namespaces/ns?fieldSelector=metadata.name=foo =>
requestInfo.Name = "foo",
requestInfo.Verb = "list"
/api/v1/secrets/namespaces/ns?fieldSelector=metadata.name=foo&watch=true =>
requestInfo.Name = "foo",
requestInfo.Verb = "list"
```
```release-note
list/watch API requests with a fieldSelector that specifies `metadata.name` can now be authorized as requests for an individual named resource
```

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.
```

We had IDRange in both types prior 9440a68744 commit that splitted it
into UserIDRange/GroupIDRange. Later, in c91a12d205 commit we had to
revert this changes because they broke backward compatibility but
UserIDRange/GroupIDRange struct left in the internal type.
This commit removes these leftovers and reduces the differences
between internal and external types.

Update all script shebangs to use /usr/bin/env interpreter instead of /bin/interpreter
This is required to support systems where bash doesn't reside in /bin (such as NixOS, or the *BSD family) and allow users to specify a different interpreter version through $PATH manipulation.

```release-note
Use /usr/bin/env in all script shebangs to increase portability.
