Since the behavior is now changed, and the old behavior leaked objects,
this adds a new comment about how Replace works.

This is useful to both reduce the code complexity, and to ensure clients
get the "newest" version of an object known when its deleted. This is
all best-effort, but for clients it makes more sense giving them the
newest object they observed rather than an old one.
This is especially useful when an object is recreated. eg.
Object A with key K is in the KnownObjects store;
- DELETE delta for A is queued with key K
- CREATE delta for B is queued with key K
- Replace without any object with key K in it.
In this situation its better to create a DELETE delta with
DeletedFinalStateUnknown with B (with this patch), than it is to give
the client an DeletedFinalStateUnknown with A (without this patch).

This fixes an issue where a relist could result in a DELETED delta
with an object wrapped in a DeletedFinalStateUnknown object; and then on
the next relist, it would wrap that object inside another
DeletedFinalStateUnknown, leaving the user with a "double" layer
of DeletedFinalStateUnknown's.

Kubernetes-commit: a818874dce54226ecc8ef384ff8b4c82aa6aaa85
This fixes a race condition when a "short lived" object
is created and the create event is still present on the queue
when a relist replaces the state. Previously that would lead in the
object being leaked.
The way this could happen is roughly;
1. new Object is added O, agent gets CREATED event for it
2. watch is terminated, and the agent runs a new list, L
3. CREATE event for O is still on the queue to be processed.
4. informer replaces the old data in store with L, and O is not in L
- Since O is not in the store, and not in the list L, no DELETED event
is queued
5. CREATE event for O is still on the queue to be processed.
6. CREATE event for O is processed
7. O is <leaked>; its present in the cache but not in k8s.
With this patch, on step 4. above it would create a DELETED event
ensuring that the object will be removed.

Ginkgo v2.1.6 adds ginkgo.SuppressProgressReporting which is needed
to suppress too verbose output each time the ReportAfterEach of the custom
progress reporter is invoked.
Kubernetes-commit: a440c257a9119c899af18f424e8e4daeb0078564
This change updates the transport.Config .Dial and .TLS.GetCert fields
to use a struct wrapper. This indirection via a pointer allows the
functions to be compared and thus makes them valid to use as map keys.
This change is then leveraged by the existing global exec auth and TLS
config caches to return the same authenticator and TLS config even when
distinct but identical rest configs were used to create distinct
clientsets.

The functionality provided by the finalURLTemplate is still used by
certain external projects to track the request latency for requests
performed to kube-apiserver.
Using a template of the URL, instead of the URL itself, prevents the
explosion of label cardinality in exposed metrics since it aggregates
the URLs in a way that common URLs requests are reported as being the
same.
This reverts commit bebf5a608f68523fc430a44f6db26b16022dc862.
