> 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.
