[ONOS-3080] ONOSFW consists of three parts vtn/vtnweb/vtnrsc. Before we
need deploy three applications, but now vtn/vtnweb/vtnrsc as three
bundles are packaged as a single application. instead to install three
application. of cource if the other apps want to depend on any one of
three bundles, it can do.
