It seems valuable to be able to provide hand-written docs for these
first-level directories, and if don't want them, the generated doc.go
files are not actually very helpful.
This commit also adds new doc.go files for client-go listers/ and
informers/.

While refactoring the backoff manager to simplify and unify the code
in wait a race condition was encountered in
TestSharedInformerWatchDisruption. The new implementation failed
because the fake clock was not propagated to the backoff managers
when the reflector was used in a controller. After ensuring the
mangaers, reflector, controller, and informer shared the same
clock the test needed was updated to avoid the race condition by
advancing the fake clock and adding real sleeps to wait for
asynchronous propagation of the various goroutines in the controller.
Due to the deep structure of informers it is difficult to inject
hooks to avoid having to perform sleeps. At a minimum the FakeClock
interface should allow a caller to determine the number of waiting
timers (to avoid the first sleep).

Add a "lazy" type to track when an update is needed. It uses a nested
locking technique to avoid extra evaluation calls.

The new ginkgo release adds sorting of specs. This was triggered by
the observation that parallel test execution of Kubernetes E2E tests
sometimes ran the same spec twice and (presumably) other specs not at all
because spec order was random due to iteration over a map.
Sorting should avoid that problem.

Currently, watch package embeds context deadlineexceeded error
in it's own error using `%v`, as can be seen in here;
`fmt.Errorf("UntilWithSync: unable to sync caches: %v", ctx.Err())`
However, consumers of this function can not use
`errors.Is(err, context.DeadlineExceeded)` due this `%v`.
To let consumers can distinguish context deadlineexceeded errors,
this PR changes error embedding format to `%w`.

Fake discovery should return an error if an error-returning reactor was prepended.
This is relevant e.g. for unit tests which test a function which relies
on discovery to check if an API Server is available.
Matches existing behavior of other fake types, for example fake_namespace.
Adds unit test coverage as well.

Currently, when the remote connection is unexpected closed, forward() prints an error message saying "lost connection to pod" via runtime.HandleError, but then it returns nil for the error.
This prevents the caller from being able to handle this error differently.
This commit changes forward() to return the "lost connection to pod" error so that it can be handled by the caller.
Making this change enables kubectl port-forward to exit with code 1, instead of 0, which is the expected behavior for a command that has failed.

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.

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.
