描述

What would you like to be added?

Kubernetes traffic generator should use Watch without ProgressNotify (like apiserver does for events) and without PrevKV (like it does for compact_rev_key). The latter will also help cover the case of non-recursive watch.

In case of Watches on events resource, traffic generator could also open multiple watch streams within the same gRPC stream to better mimic what apiserver does.

Work on this was partially started in https://github.com/etcd-io/etcd/pull/20577

Why is this needed?

Part of https://github.com/etcd-io/etcd/issues/15820 and https://github.com/etcd-io/etcd/issues/20182

研究方向
The issue requires adding Watch without ProgressNotify and PrevKV to the Kubernetes traffic generator in etcd. Work was partially started in PR #20577, which should be reviewed first. The changes should mimic how apiserver uses Watch on events resource and cover non recursive watch. Relevant code is likely in the tools/traffic generator directory. Comments on the issue provide some discussion on implementation details.
