Description of problem: From a test/debug perspective, it would be nice if it was easy to set a global password for all services, databases, keys, etc. This is something you can do manually for each specific password, but that is cumbersome on the command line. So in short, a --password option that is used to fan out to all other relevant parameters would be good. If this is impossible, a helper script could be used. One that calls packstack under the covers with all of the appropriate individual password cli arguments.

Just as an observation: it might just me being paranoid but it might be dangerous to have the same password for the mysql root user and passwords that are pottentialy to be given to other users. I know packstack is PoC tool but that shouldn't stop us for thinking about basic security if we can.
