It allows us to allocate a single buffer for the entire watch session and release it when a watch connection is closed.
Previously memory was allocated for every object serialization putting a lot of pressure on GC and consuming more memory than needed.

Implements server side field validation behind the
`ServerSideFieldValidation` feature gate. With the
feature enabled, any create/update/patch request
with the `fieldValidation` query param set to
"Strict" will error if the object in the request
body have unknown fields. A value of "Warn"
(also the default when the feautre is enabled)
will succeed the request with a warning.
When the feature is disabled (or the query param
has a value of "Ignore"), the request will succeed
as it previously had with no indications of any
unknown or duplicate fields.

addresses feedback by adding a test to make sure that the manager pipeline will not return the same instance used as input, and that the output does not input managedFields

drop the managed fields of the objects from the audit entries when we
are logging request and response bodies.

Replace the forked totalAnnotationSizeLimitB with
apimachineryvalidation.TotalAnnotationSizeLimitB.

To support CSA and SSA interoperability, SSA updates the CSA
last-applied annotation.
This change ensures we don't set a big last-applied annotation if the
value is over the annotation limits.
Also, make sure that it's possible to opt-out of this behavior by
setting the CSA annotation to "" the empty string.

Not all objects provide metadata. There might be extention servers that allow for creating objects without the metadata field.
This PR changes the managedFileds admission to deal with objects without the metadata field.
Object without that field will be passed directly to the wrapped admission controller for further validation.

This is to prevent the ScaleHandler to drop the entry. In this way
entries just get ignored.

- Test all versions to make sure each resource version is in the
mappings
- Fail when request info contains an unrecognized version. We have tests
that guarantee that all known versions are in the mappings. If we
get a version in request info that is not there we should fail fast to
prevent inconsistent behaviour (e.g. for some reason the mappings is
not up to date).
Ensure all known versions are in mappings

This field is useful to namespace the managed field entries of a
subresource and differentiate them from the ones of the main resource.

- when we forward the request to the aggregated server, set the audit
ID in the new request header. This allows audit logs from aggregated
apiservers to be correlated with the kube-apiserver.
- use the audit ID in the current tracer
- use the audit ID in httplog
- when a request panics, log an error with the audit ID.

Ensure that all label selectors are treated as atomic values,
to exclude situations when selectors are being corrupted by
different actors attempting to apply their overlapping definition
for this field with server-side-apply.

Adds and implements ResetFieldsProvder interface in order to ensure that
the fieldmanager no longer owns fields that get reset before the object
is persisted.

- as soon as a request is received by the apiserver, determine the
timeout of the request and set a new request context with the deadline.
- the timeout filter that times out non-long-running requests should
use the request context as opposed to a fixed 60s wait today.
- admission and storage layer uses the same request context with the
deadline specified.
we use the default timeout enforced by the apiserver:
- if the user has specified a timeout of 0s, this implies no timeout on the user's part.
- if the user has specified a timeout that exceeds the maximum deadline allowed by the apiserver.

apiserver dedups and adds warning in CREATE/UPDATE/PATCH requests;
also handles duplication caused by mutating admission.
Kubernetes-commit: 8bcf34a203efa596ac3b65da9afd6b6c764e78a9
for CREATE and UPDATE requests, we check duplication before managedFields
update, and after mutating admission; for PATCH requests, we check
duplication after mutating admission

PATCH verb is used when creating a namespace using server-side apply,
while POST verb is used when creating a namespace using client-side
apply.
The difference in path between the two ways to create a namespace led to
an inconsistency when calling webhooks. When server-side apply is used,
the request sent to webhooks has the field "namespace" populated with
the name of namespace being created. On the other hand, when using
client-side apply the "namespace" field is omitted.
This commit aims to make the behaviour consistent and populates the
"namespace" field when creating a namespace using POST verb (i.e.
client-side apply).
