Fix debian init

[dizzythinks]

When running the Debian init_script manually the do_start function would immediately exit with a failure on the first test in the for loop sequence even if the process was actually running.

for i in `seq 1 30`; do
    if ! start-stop-daemon --quiet --stop --test --pidfile $PIDFILE --exec $DAEMON --user $USER; then
        echo " FAIL: consul process died"
        return 2
    fi

Have altered this so it captures the return code and sleeps before proceeding through the for loop.

Ug. I hate init scripts.

They can be a pain it's true! :-)
