Automate stress test for the platform

[RicCapUnitn]

Automate DB migration and script launch to easily run stress tests on the platform.

Acceptance criteria: a script will be provided (or in Makefile) that runs the test population generation script, imports the data into the database and runs the test suite. Each build should provide a report that contains at least:

• memory usage
• clock time
• number of queries launched
