Fixes: kubernetes#90581 (the first part)
When `Close()` is invoked on an empty queue, the control loop inside `Pop()` has a small chance of missing the signal and blocks indefinitely due to a race condition. This PR eliminates the race and allows the control loop inside any blocking `Pop()` to successfully exit after Close() is called.

With support of http, https, and socks5 proxy support. We already
support configuring this via environmnet variables, but this approach
becomes inconvenient dealing with multiple clusters on different
networks, that require different proxies to connect to. Most solutions
require wrapping clients (like kubectl) in bash scripts.

When creating an informer, this adds a way to add custom error handling, so that
Kubernetes tooling can properly surface the errors to the end user.

Removed the incorrect promise of coherency in the answer to a query to
an informer's local cache. Removed the definition of "collection
state", because it was only used in the now-removed promise. Added a
remark about ordering of states that appear in an informer's local
cache.
Brushed up the commentary on resync period. Changed the relevant
parameter of NewSharedInformer to have the same name as the
corresponding parameter to NewSharedIndexInformer.

Also updated the comment inside processorListener::run, to restore
accuracy about how long the delay is.

Background:
Before this change, DeltaFIFO emits the Sync DeltaType on Resync() and
Replace(). Seperately, the SharedInformer will only pass that event
on to handlers that have a ResyncInterval and are due for Resync. This
can cause updates to be lost if an object changes as part of the Replace(),
as it may be incorrectly discarded if the handler does not want a Resync.
What this change does:
Creates a new DeltaType, Replaced, which is emitted by DeltaFIFO on
Replace(). For backwards compatability concerns, the old behavior of
always emitting Sync is preserved unless explicity overridden.
As a result, if an object changes (or is added) on Replace(), now all
SharedInformer handlers will get a correct Add() or Update()
notification.
One additional side-effect is that handlers which do not ever want
Resyncs will now see them for all objects that have not changed during
the Replace.

This adds ResetWatch() to the FakeControllerSource, which lets the
controller simulate a re-list-and-watch.
