Subject: [PATCH] Prepare for using standard python tests

Add simple script to setup mysql and postgresql databases,
this script can be run by users during testing and will be
run by CI systems for specific setup before running unit tests.

This allows us to change in project-config the python-db jobs to
python-jobs since python-jobs will call this script initially.

Update README for this.
