Update git submodules

* Update plugins/replication from branch 'master'
  to d8194b291bb0433b5c3abe059ebad6f00fcb3a22
  - Generalize replication configuration type
    
    Configuration is tightly coupled to destination configuration, however
    this can be abstracted away so that different type of configurations can
    be plugged in at runtime.
    
    Introduce the concept of RemoteConfiguration, so that pull-replication
    can leverage the existing configuration classes and auto-reload
    mechanism.
