Review Comment:
   The mechanism in here for "automatically" updating a local conf is to update 
line 95 and line 103 to increment the version number, so that the next time 
someone runs the regtests they'll automatically pick up the newest set of 
config values.
   
   However, there's the risk that if someone manually updated the 
spark-defaults file with customizations then the update will comment out all 
such customizations.
   
   I guess it's a balance between having a consistent conf for everyone running 
the tests vs allowing people to have persistent differences.
   
   If people only run via docker then the point is moot though, so maybe the 
whole auto-updating mechanic in here can be considered obsolete.
