* Update plugins/replication from branch 'master'

  - Change default for the  replicateOnStartup to false
    
    Now that replication events are persistent and non-finished replications
    rescheduled after plugin restart the replicateOnStartup feature becomes
    less important. We can change the default value for this option to
    false.

  - Don't lose ref-updated events on plugin restart
    
    When a ref-updated event is received, persist the event in the directory
    defined by the replication.eventsDirectory. When the updated ref is
    replicated deleted the persisted event.
    
    If replication queue is non-empty and plugin gets stopped, ref updates
    will not be replicated and, therefore, the persisted events will not get
    deleted. When the plugin starts it will schedule replication for all
    persisted events and delete them.
    
    This change provides two benefits:
    * no ref-updated events are lost on plugin restart
    * eliminate need for the replicateOnStartup=true setting which schedules
      replication of all refs for all projects and typically creates a humongous
      replication queue on every plugin restart.
