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.

- 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).

If a request tries to change managedFields, the response returns the
managedField of the live object.

previously all sorts of errors including a data race were possible because deferredResponseWriter resets the writer and returns it to the pool.
an attempt to write to a nil writer will lead to "invalid memory address or nil pointer dereference"
sharing the same instance of deferredResponseWriter might lead to "index out of range [43] with length 30" and "recovered from err index > windowEnd" errors
