[Trunk | Authorization Library]:

1. Added folder /controllers.
2. AuthorizationLibraryCheckDeployController.java: [NEW] Controller added and 
	a. "hello()" method (@RequestMapping(value = {"", "/health_check"}, method = RequestMethod.GET)) which just prints and returns a greeting message.
	b. "checkEverything()" method @RequestMapping(value = "/health_check/advanced", method = RequestMethod.GET) only accessible by PORTAL ADMINS which checks connection with db and prints properties.
