We see long reactor stalls from `logalloc::prime_segment_pool` in debug mode yet the stall detector's purpose is to detect reactor stalls during normal operation where they can increase the latency of other queries running in parallel. Since this change doesn't actually fix the stalls but rather hides them, the following annotations will just refrence the respective github issues rather than auto-close them. Refs #7150 Refs #5192 Refs #5960 Restore blocked_reactor_notify_ms right before starting storage_proxy. Once storage_proxy is up, this node affects cluster latency, and so stalls should be reported so they can be fixed.
