OpenSDI-Manager code refactor

This change include last NRL code and make it those changes to let you work on different projects:

* Package rename nrl --> opensdi (pom and classes)
* Change modules to separe the common part and the NRL specific part
* Geobatch conection refactor to centralize and use the logged user
* Property overrider to write all parameters on the final deploy
* Parametrize jetty port on webapplications to let you execute in different ports by console with parameter like '-Djetty.port=10081' (default it's 9191 for admin and 10081 for geobatch)
