The current default NumMissedTableIAmAliveLimit (2) and IAmAliveTablePublishTimeout (5 min) values are very conservative. This can result in downtime of about 10 minutes after a full cluster crash + restart.

This PR changes the values to 3 & 30s by default, reducing the downtime to closer to 90s after a catastrophic failure scenario.
