DISTMYSQL-141: In complicated environments, such as 3 or more datacenters, or when each server has more than 2 intermediary masters, Orchestrator could miss replication delays in one or more datacenters. This was happening due to a hard-coded limitation of two intermediary masters to check for the replication delay. This is now fixed.
