- Implemented API for streaming for the `etcd` store implementation.
  When `sendInitialEvents ListOption` is set together with `watch=true`, it begins the watch stream with synthetic init events followed by a synthetic `Bookmark`, after which the server continues streaming events. ([#119557](https://github.com/kubernetes/kubernetes/pull/119557), [@p0lyn0mial](https://github.com/p0lyn0mial))

NOTE: Not all test frameworks play well with filtering. Some advanced, synthetic tests may not be fully compatible.
However, the vast majority of tests and use cases work perfectly well with Gradle's filtering mechanism.
