A Java Util Preferences etcd backend implementation.

Etcd is one of the main configuration cloud oriented key/value backends. The java applications will need to

With this implementation the java applications will, transparently, use etcd as backend to store and retrieve application configuration vía java.util.prefs.

A sample, get the application database driver and url from application preferences:

Preferences applicationPref = Preferences.systemRoot();
String driver = userPrefs.get("database.driver", "org.postgresql.Driver");
String url    = userPrefs.get("database.url",    "jdbc:postgresql://localhost:5740/myDb");

This implementation abstracts the application the problems about interact with etcd, use and standard Java API and does not require to use external libraries.
