> As work continues on HADOOP-13397, it's become evident that we need better hooks to start daemons as specifically configured users. Via the (command)_(subcommand)_USER environment variables in 3.x, we actually have a standardized way to do that. This in turn means we can make the sbin scripts super functional with a bit of updating:
> * Consolidate start-dfs.sh and start-secure-dns.sh into one script
> * Make start-\*.sh and stop-\*.sh know how to switch users when run as root
> * Undeprecate start/stop-all.sh so that it could be used as root for production purposes and as a single user for non-production users
