Lift embedded structure out of eviction-related KubeletConfiguration fields
- Changes the following KubeletConfiguration fields from `string` to
`map[string]string`:
- `EvictionHard`
- `EvictionSoft`
- `EvictionSoftGracePeriod`
- `EvictionMinimumReclaim`
- Adds flag parsing shims to maintain Kubelet's public flags API, while
enabling structured input in the file API.
- Also removes `kubeletconfig.ConfigurationMap`, which was an ad-hoc flag
parsing shim living in the kubeletconfig API group, and replaces it
with the `MapStringString` shim introduced in this PR. Flag parsing
shims belong in a common place, not in the kubeletconfig API.
I manually audited these to ensure that this wouldn't cause errors
parsing the command line for syntax that would have previously been
error free (`kubeletconfig.ConfigurationMap` was unique in that it
allowed keys to be provided on the CLI without values. I believe this was
done in `flags.ConfigurationMap` to facilitate the `--node-labels` flag,
which rightfully accepts value-free keys, and that this shim was then
just copied to `kubeletconfig`). Fortunately, the affected fields
(`ExperimentalQOSReserved`, `SystemReserved`, and `KubeReserved`) expect
non-empty strings in the values of the map, and as a result passing the
empty string is already an error. Thus requiring keys shouldn't break
anyone's scripts.
- Updates code and tests accordingly.
Regarding eviction operators, directionality is already implicit in the
signal type (for a given signal, the decision to evict will be made when
crossing the threshold from either above or below, never both). There is
no need to expose an operator, such as `<`, in the API. By changing
`EvictionHard` and `EvictionSoft` to `map[string]string`, this PR
simplifies the experience of working with these fields via the
`KubeletConfiguration` type. Again, flags stay the same.
Other things:
- There is another flag parsing shim, `flags.ConfigurationMap`, from the
shared flag utility. The `NodeLabels` field still uses
`flags.ConfigurationMap`. This PR moves the allocation of the
`map[string]string` for the `NodeLabels` field from
`AddKubeletConfigFlags` to the defaulter for the external
`KubeletConfiguration` type. Flags are layered on top of an internal
object that has undergone conversion from a defaulted external object,
which means that previously the mere registration of flags would have
overwritten any previously-defined defaults for `NodeLabels` (fortunately
there were none).
Related: #53833 (lifting embedded structures out of string fields is part of getting this API to beta)
```release-note
The EvictionHard, EvictionSoft, EvictionSoftGracePeriod, EvictionMinimumReclaim, SystemReserved, and KubeReserved fields in the KubeletConfiguration object (kubeletconfig/v1alpha1) are now of type map[string]string, which facilitates writing JSON and YAML files.

add back defaulting for parameter decoding
At the beginning of 1.7, we removed the last "conversion causes defaulting". This broke the "default to true" behavior for exec and attach options, but we didn't notice. This removes the broken defaulter (you can default a non-point bool to true on an object) and adds back defaulting to parameter codecs.

Some errors are invoked outside of negotiation. These errors should
still have a kind and apiVersion (which is only set by structured
encoders, not always availabe). Ensure that all errors by default get a
status kind and version set.

code-generator: complete PkgName, GroupName, GoName seperation
... in client-gen, informer-gen, lister-gen. Follow-up of https://github.com/kubernetes/kubernetes/pull/54950.
Before this PR, the generated code was broken for internal types and for group package names that were no valid Go identifiers.
This PR completes the separation in the following sense:
- GroupNames are domain-like logical name for the group. Only the first segment is used as default for GoName
- PkgName is the directory name. All packages in client, informer, lister re-use this for packages.
- GoName is the Go identifier (CamelCase) used to reference the group, e.g. in the interface names, in the clientsets etc. Moreover it is used for package import aliases.
Note: this PR **does not** change the generated code in Kubernetes, only the examples in k8s.io/code-generator.
```release-note
Fix code-generators to produce correct code when GroupName, PackageName and/or GoName differ.

Move the namespace selector code to package webhook/namespace
Move the conversion related code to package to webhook/versioned
Move errors related code to package webhook/errors
Move admission review related code to package webhook/request
Introduce the v1alpha1 version to the Kubernetes storage API. And add a
new VolumeAttachment object to that version. This object will initially
be used only by the new CSI Volume Plugin. Eventually existing volume
plugins can be refactored to use it too.
Moved client and kubeconfig related code to webhook/config;
Moved the rule matcher to webhook/rules;
Left TODOs saying we are going to move some other common utilities;
Other code is moved to webhook/validation.
