Update git submodules

* Update plugins/replication from branch 'master'
  to 4296f7364429ffe5e537756199cd14daab2d3353
  - Add --ref option to start command
    
    Users can now trigger replication for a specific reference using the
    --ref <RefName> option. This allows for targeted replication of
    individual branches or tags rather than forcing a full project sync.
    
    Example usage:
      ssh -p 29418 host replication start --ref refs/heads/master my-project
    
    Change-Id: If6d208411e2a1645fff4f7a6d2e6c5428b87e3f3
    Release-Notes: Add --ref <RefName> option to start command
