Update git submodules

* Update plugins/replication from branch 'master'
  to 56ea64394e8a58b213c0d859c219036fe6c78b0c
  - Set SSH timeouts from configuration file
    
    It looks like during the refactoring in I253a6d94, `sshCommandTimeout`
    and `sshConnectionTimeout` fields were not initialized with values from
    the `replication.config`.
    
    This is restoring code present before change mentioned above.
