Support for SFTP is required.

[Tobias Schlauch]

The following is to do:
- Create sftp persistence adapter which supports handling of files/directories
- Add data store configuration
 - Extend XML schema
 - Add corresponding Python handler code
 - Extensions to the admin client are not required
- Provide sufficient tests

[Tobias Schlauch (tobias-schlauch)]

Configuration is possible with the administration client as well. You just have to define a FTP store and set the right data location. I.e., use the sftp scheme (e.g. sftp://server.de/home/path).
