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

Update devref for this.
