Clarify config parameters/environment variables
As mentioned in the comments, ideally this script can be used as the basis for an ONOS service in a variety of environments. Out of the box it should work on Linux with either init.d or with systemd's init.d compatibility. It can also be called by an upstart configuration or a systemd configuration. In the future we should probably remove start-stop-daemon, since that seems to be a linux-ism. Then we could use this script on BSD, OS X, etc.. Change-Id: I9c701c95991448fa7ddf0d84d379a4cac56cfc5f
