All the recent changes to replication code have slowed down some things in replication temporarily. Because of this there has been an increase in flaky test failures due to timing out waiting for various replication events (electing a primary is the most common). Rather than 1 ticket per failure like this, this ticket will be an umbrella ticket for all these types of failures. For each of these tests we should either remove them and replace them with unit tests, or verify that they pass consistently after we've switched fully over to the new replication code, which should speed things back up.
