* apiserver/storage/continue: intro PrepareContinueToken
PrepareContinueToken prepares optional
parameters for retrieving additional results for a paginated request.
This function sets up parameters that a client can use to fetch the remaining results
from the server if they are available.
* apiserver/storage/etcd3: refactor to use PrepareContinueToken

For request like '/api/v1/watch/namespaces/*', don't set scope.namespace.
Because the func `addWatcher` add a watcher to allWatchers with the value `scope.namespace` not empty.
But the function `dispatchEvent` dispatch event with an empty namespace.

This library release makes a number of behaviors configurable in ways that are required for CBOR
support in Kubernetes.

The internal informer populates the RV as soon as it conducts
The first successful sync with the underlying store.
The cache must wait until this first sync is completed to be deemed ready.
Since we cannot send a bookmark when the lastProcessedResourceVersion is 0,
we poll aggressively for the first list RV before entering the dispatch loop.

Implementing custom marshaling on several API types for CBOR makes the upstream CBOR library an
indirect dependency of several staging modules.

For case of SendInitialEvents, a buffer of objects is created. That
process takes a significant amount of memory and CPU when the resource
is of a large volume. Many objects may be not relevant when key is provided.
This commit applies key when composing the buffer for SendInitialEvents.

The canonical import for json-patch v4 is
gopkg.in/evanphx/json-patch.v4 (see
https://github.com/evanphx/json-patch/blob/master/README.md#get-it for
reference).
Using the v4-specific path should also reduce the risk of unwanted v5
upgrade attempts, because they won't be offered as automated upgrades
by dependency upgrade management tools, and they won't happen through
indirect dependencies (see
https://github.com/kubernetes/kubernetes/pull/120327 for context).

There is no benefit of having RWMutex as we have one reader and multiple
writers. In such cases RWMutex has worse performance than Mutex.

Signal is not needed as we never need to wake up when the waiting
is lowered, only when increased.

Ticker behaves differently from what we want, we need a stable period
interval, but ticker doesn't provide that. From NewTicker docstring:
```
The ticker will adjust the time interval or drop ticks to make up for slow receivers.
```
Unfortunatelly there is no way to test it as the FakeClock doesn't
follow the real ticker behavior.

Ginkgo v2.18.0 allows tweaking the output so that
it's easier to follow while a job runs in
Prow (https://github.com/onsi/ginkgo/issues/1347). Using this in
hack/ginkgo-e2e.sh will follow in a separate commit.
Gomega gets bumped to the latest release to keep it up-to-date.
Ginkgo v1.19.0 adds support for --label-filter with labels that represent
sets (like our Feature:<Foo>).
