- add serverhostname parameter to the component daemon manifests to
  specify to which zarafa server they should connect (but the
  parameter is not used anywhere at the moment ;))
- correct some indention
- add missing dependencies so that the configuration files will
  be updated after the software packages have been installed and
  not before (augeas does not care if the file exists, it will
  create it if necessary)
Notify the daemon service when updating the configuration file
to reload it.
