* Update plugins/replication from branch 'stable-3.5'
  to 20f1c213bc2c56bddce03cf8d4b0b63bd609fc20
  - Demote rename errors when distributor is enabled
    
    Since rename errors for Tasks is common and normal when running with a
    multi-primary setup, demote them to "atFine()" level when the
    distributor is enabled. This avoids making the logs extrememly noisy
    during normal multi-primary operation.
