Move mysql table create ddl into script

I think it's easier to manage having different query templates this way.
Otherwise when you change the DSS_PATH, you have to copy all the .ddl
files too.  Will have to reintroduce the nitro specific files another
way.
Update mysql start and stop scripts

Use mysqladmin ping to determine when the daemon is running or not.
Hopefully a better way than using sleeps.
Save mysql system variables
Save mysql log in correct location on load test
