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.
