[20/60] main: Introduce the 'OnlineCheck{Failures,Successes}Threshold' settings.

Commit Message

Grant Erickson Dec. 21, 2023, 6:16 a.m. UTC

When both "EnableOnlineCheck" and "EnableOnlineToReadyTransition" are
asserted, "OnlineCheckFailuresThreshold" is the number of failed
back-to-back "ready" to "online" HTTP-based Internet reachability
checks that will be allowed before marking a service as "failed" from
a reachability perspective, sorting it at a lower priority than other
services not so marked.

When both "EnableOnlineCheck" and "EnableOnlineToReadyTransition" are
asserted, "OnlineCheckSuccessesThreshold" is the number of successful
back-to-back "ready" to "online" HTTP-based Internet reachability
checks that must be met before clearing a service as "failed" from a
reachability perspective and allowing it to transition to the "online"
state again, allowing it to sort back to a higher priority relative to
other network services.
