genericapiserver/api/filters: cut off pkg/api dependency and fix timeout status
The timeout status did not have a proper group version and verb. With the `RequestInfo` available we can easily create a proper status object.
As a side-product we cut off the dependency to `pkg/api` from `genericapiserver/api/filters`.
Follow-up with version negotiation is here: https://github.com/kubernetes/kubernetes/pull/40211

Improve TerminationMessagePath to be more flexible
* Support `terminationMessagePolicy: fallbackToLogsOnError` which allows pod authors to get useful information from containers as per kubernetes/community#154
* Set an upper bound on the size of the termination message path or log output to prevent callers from DoSing the master
* Add tests for running as root, non-root, and for the new terminationMessagePolicy cases.
I set the limit to 4096 bytes, but this may be too high for large pod containers. Probably need to set an absolute bound, i.e. max message size allowed is 20k total, and we truncate if we're above that limit.
Fixes#31839, #23569
```release-note
A new field `terminationMessagePolicy` has been added to containers that allows a user to request `FallbackToLogsOnError`, which will read from the container's logs to populate the termination message if the user does not write to the termination message log file. The termination message file is now properly readable for end users and has a maximum size (4k bytes) to prevent abuse. Each pod may have up to 12k bytes of termination messages before the contents of each will be truncated.
```
These files have been created lately, so we don't have much information
about them anyway, so let's just:
- Remove assignees and make them approvers
- Copy approves as reviewers
Enforce the following limits:
12kb for total message length in container status
4kb for the termination message path file
2kb or 80 lines (whichever is shorter) from the log on error
Fallback to log output if the user requests it.

Make generic registry easier to understand
**What this PR does / why we need it**:
This PR makes the generic registry and some areas of the api REST abstractions easier to understand by adding and clarifying comments. These comments are based on digging that was done to implement a new API server and REST storage for resources in a wholly-new API group.
**Release note**:
```release-note
NONE

make client-go tools/auth and tools/clientcmd authoritative
These moved easily. Pure mechanical. I'll have a couple snip pulls for some of the more complicated packages. `pkg/util/homedir` was a transitive that moved with. It was only used in `kubectl` and you'd need it to be consistent with `clientcmd` loading order.

Add the ability to edit fields within a config map.
Addresses part of https://github.com/kubernetes/kubernetes/issues/36222
Example command:
```console
$ kubectl edit configmap foo --config-map-data=bar
```
Will open the data element named `bar` in the `ConfigMap` named `foo` in `$EDITOR`, the edited contents are then updated back to the config map.

```release-note
Add a special purpose tool for editing individual fields in a ConfigMap with kubectl

Emit warning event when CronJob cannot determine starting time
**What this PR does / why we need it**:
In #39608, we've modified the error message for when a CronJob has too many unmet starting times to enumerate to figure out the next starting time. This makes it more "actionable", and the user can now set a deadline to avoid running into this. However, the error message is still only controller level AFAIK and thus not exposed to the user. From his perspective, there is no way to tell why the CronJob is not scheduling the next instance.
The PR adds a warning event in addition to the error in the controller manager's log.
**Which issue this PR fixes**: This is an addition to PR #39608 regarding #36311.

`error validating "/home/shiywang/template/test.yaml": error validating data: field ports for v1.ServiceSpec: is required; if you choose to ignore these errors, turn validation off with --validate=false`
still need add some unit test, plz don't test now

Set custom PollingDelay of 5 seconds for Azure VirtualMachinesClient
The default polling delay of 1 minute results in very long delays when
an Azure Disk is attached to a node. It gets worse as go-autorest
doubles the default delay to 2 minutes.
Please see: https://github.com/kubernetes/kubernetes/issues/35180#issuecomment-273085063
Only the PollingDelay for VirtualMachinesClient is modified here to
avoid too much pressure on Azure quotas.
Release Nodes:
```release-note
Reduce time needed to attach Azure disks

Invalidate updates to non-convertible selectors

@deads2k @lavalamp @smarterclayton @bgrant0607 @liggitt @mfojtik
First commit contains the necessary validation for replication controllers with non-convertible selectors.
Second commit updates the name for the annotation added during conversion since it is invalid currently:
