autofailover 2 minutes delay when failover timeout is set to 30 seconds

Details

Description

when one of the nodes go missing and stop responding autofailover will take an extra minute or two to automatically failover the node

more information from Aliaksey about this bug:


Just tested normal shutdown case. Indeed it was longer than expected. Our implementation needs extra 2 hearbeat periods to actually confirm that other nodes are up so it explains 10 seconds more then 30. But in my testing it was around 50 seconds when timeout was set to 30 seconds.

correction: I was referring to branch-18. I.e. 1.8.2 which has quick failover

No. 1.8.1 was (at least initially) supposed for simple fixes. Running replicators on replicas was deemed not simple. We were not allowed to have this on 1.8.1. 1.8.2 if it will be released will have this fix.

Let's move this into the 2.0 branch. I assume the 1.8.2 fix has been reviewed and tested already. Thanks.

2.0 automagically has this as everything in branch-18 was merged to 2.0
