> It is a while since these scripts were touched. Giving them a spring
> cleaning and seeing if can make them return error codes on failure (seems
> like style previous was that the operator would watch the output and react to
> it but I see cases where tools want to call these scripts and they want
> return code to indicate whether the rolling upgrade worked or not). Also,
> see if can make the rolling restart faster since one-by-one while minimally
> disruptive and 'safe', it is slow one clusters of hundreds of nodes.
