    Description

      The XDCR test will monitor replication_changes_left after XDCR starts. In this run, xdcr reported replication_changes_left = 0, and it resulted in wrong performance number reported. 

      Avg. initial XDCR rate (items/sec), 5 -> 5 (2 source nozzles, 4 target nozzles), 1 bucket x 1G x 1KB, DGM, s=1, c=1000

      build: 7.1.0-1885

      In a good run, replication_changes_left will decrease gradually.
