Optional configmaps and secrets
Allow configmaps and secrets for environment variables and volume sources to be optional
Implements approved proposal c9f881b7bb
Release note:
```release-note
Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding `optional: true` to the volume or environment variable source specifications.

Allows kubectl create -f to filter by selector.
From #32544.
The underlying `seletor` infrastructrue was implemented by #32599. The test is basically copy-paste of the corresponding test for `kubectl apply -f -l`.
```release-note
kubectl create now accepts the label selector flag for filtering objects to create
```

Move ListOptions into meta
metav1.ListOptions is moving to k8s.io/apimachinery/pkg/apis/meta/v1. The internal version will be reserved for server use (clients will use metav1), and all references changed.
Also, all references to the Namespace* constants are being moved to point to metav1.
Move over only the conversions that are needed, create a new scheme that
is private to meta and only accessible via ParameterCodec. Move half of
pkg/util/labels/.readonly to pkg/apis/meta/v1/labels.go
The previous option was not serializable, and was used in questionable
scenarios to represent what we also use Everything() for. The individual
context needs to make the decision about everything vs nothing (and
nothing has no real concept in our API today) so this seems safe.

Remove federated-image.tag from the .gitignore file.
This generated version metadata file was being written to a source
directory and caused a lot of pain. We are moving to a world where
this file is generated in the build/output artifacts directory and
also possibly looking at ways to entirely remove the federation
specific versions file. This is in-line with that goal of removing
the dependency on federated-image.tag file.

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.

OWNERS: Update latest OWNERS files
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

Only run gcloud as root if we plan to change something.
Fixes bug introduced in #36292 @jlowdermilk @ixdy
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.
