[test][setup] Move test_XXX database configuration to setup SQL

If the configuration is placed in setup SQL set instead of README, we
don't care about.

I agree with you.
I like to include setup information in the repository as a text file.
It enables users to build/setup without using internet or GUI environment. 

> Anyway, it seems that the topic is a separated work with this change.
I think so too.
