Since the behavior is now changed, and the old behavior leaked objects,

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.

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.

The kube-apiserver validation expects the Count of an EventSeries to be
at least 2, otherwise it rejects the Event. There was is discrepancy
between the client and the server since the client was iniatizing an
EventSeries to a count of 1.
According to the original KEP, the first event emitted should have an
EventSeries set to nil and the second isomorphic event should have an
EventSeries with a count of 2. Thus, we should matcht the behavior
define by the KEP and update the client.
Also, as an effort to make the old clients compatible with the servers,
we should allow Events with an EventSeries count of 1 to prevent any
unexpected rejections.

There was a data race in the recordToSink function that caused changes
to the events cache to be overriden if events were emitted
simultaneously via Eventf calls.
The race lies in the fact that when recording an Event, there might be
multiple calls updating the cache simultaneously. The lock period is
optimized so that after updating the cache with the new Event, the lock
is unlocked until the Event is recorded on the apiserver side and then
the cache is locked again to be updated with the new value returned by
the apiserver.
The are a few problem with the approach:
1. If two identical Events are emitted successively the changes of the
second Event will override the first one. In code the following
happen:
1. Eventf(ev1)
2. Eventf(ev2)
3. Lock cache
4. Set cache[getKey(ev1)] = &ev1
5. Unlock cache
6. Lock cache
7. Update cache[getKey(ev2)] = &ev1 + Series{Count: 1}
8. Unlock cache
9. Start attempting to record the first event &ev1 on the apiserver side.
This can be mitigated by recording a copy of the Event stored in
cache instead of reusing the pointer from the cache.
2. When the Event has been recorded on the apiserver the cache is
updated again with the value of the Event returned by the server.
This update will override any changes made to the cache entry when
attempting to record the new Event since the cache was unlocked at
that time. This might lead to some inconsistencies when dealing with
EventSeries since the count may be overriden or the client might even
try to record the first isomorphic Event multiple time.
This could be mitigated with a lock that has a larger scope, but we
shouldn't want to reflect Event returned by the apiserver in the
cache in the first place since mutation could mess with the
aggregation by either allowing users to manipulate values to update
a different cache entry or even having two cache entries for the same
Events.

When attempting to record a new Event and a new Serie on the apiserver
at the same time, the patch of the Serie might happen before the Event
is actually created. In that case, we handle the error and try to create
the Event. But the Event might be created during that period of time and
it is treated as an error today. So in order to handle that scenario, we
need to retry when a Create call for a Serie results in an AlreadyExist
error.

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.
