Disable StorageNamespaceIndex feature gate when BtreeWatchCache is enabled and deprecate it
...
Previously, the cache used a map keyed by the full object key,
requiring iteration and filtering by namespace for namespace-scoped requests.
This index allowed for faster responses by avoiding this iteration.
With the introduction of the BtreeWatchCache, this optimization is no longer necessary.
The B-tree structure allows efficient prefix-based searches,
including fetching objects by namespace.
Furthermore, the B-tree returns elements ordered by key, eliminating the need for separate sorting.
Performance improvements with the BtreeWatchCache have been validated through benchmarks matching K8s scalability dimentions (see table below).
These results demonstrate that the B-tree approach provides comparable or better performance than the map with index.
Therefore, the StorageNamespaceIndex feature flag can be safely flipped to false and subsequently deprecated.
| Benchmark | Btree with Index (current) | Btree without Index | Map with Index | Map without Index (sanity check) |

client-go watch: NewIndexerInformerWatcherWithContext -> WithLogger
...
The ability to automatically stop on context cancellation was new functionality
that adds complexity and wasn't really used in Kubernetes. If someone wants
this, they can add it outside of the function.
A *WithLogger variant avoids the complexity and is consistent with
NewStreamWatcherWithLogger over in apimachinery.

They were enabled yesterday and executed seven times, with results that (so
far) seem to be fairly stable with just one run that was slower across the
board.
The links in the YAML can be used to navigate to each test case quickly. The
thresholds were chose with a 20% security margin below what seems to be a
common result.

Flip SeparateCacheWatchRPC feature gate to false and deprecate it.
...
Watch requests to etcd are mapped to a single stream that has a limited throughput.
By opening a lot of concurrent watch requests to single resource, users
could starve other watches from getting any events.
Separating the RPC was meant to protect the watch opened by cache.
However, as we are no longer planning to allow users to open watch directly to etcd,
the flag is not needed.
