Review comment:
       By docker things, do you mean we can reuse some of its functions or 
reuse the entire infrastructure to launch docker? Most of the test driver 
infrastructure is very similar to what we have in DatabaseRule, but there are 
some small things that are different. If we are to use the existing docker 
things in here, the existing metastore/dbinstall may need some fine-tuning. I 
don't want to break our existing test infrastructure so I created another 
version of the fine-tuned docker launching.
   
   With that information at hand, do you think it is better to continue with 
current version of the docker launching, or fine-tune what we had in 
DatabaseRule to adjust this new test infrastructure?
