Catalog: merge test

The genesys-catalog backend will be merged with Genesys.

This ticket is the first test merge where entities, repositories, services and controllers are copied into the Genesys project -- but keep the .catalog. package names.

The objective is to identify issues with duplicate classes, Spring configuration problems.

Test this on a new mysql database use a custom genesys.properties with:

db.hbm2ddl=true
auto.createContent=true

This issue is closed when:

1. Tests succeed
2. Database is successfully created on startup
3. http://localhost:8080 launches current Genesys frontend

Please document all problems encountered (and fixed) as comments to this issue.
