SQL now is using new schema

SQL is now compatible with DB schema in simcaqdb3

Merge branch 'fix_database_error_reporting' into 71-simcaq-implementar-backend-uc201-selecionar-localidade

Fix error handling in the database query module

Changes in this merge request
* Add proper error handling in libs/db/query_exec. Uses a catch function after each then to proper capture database errors and report them to the user.
* Add logging the error stack when a database query error occurs.
* Change error message reported in the response when a database query occurs, because the user making the request does not need to know about an internal database error.

Simobject 20160927

Created  a simulation object and a handful of tests. More tests will be needed, and sanitizing will  strongly depend on the input data format, which is not yet completely defined. A test config.json file was added to allow test database integration, and config.js was adapted to choose config file from context.

Files added:
src/libs/models/simulation.js - mongo schema for simulation;
src/libs/routes/simulation.js - express controller for simulation api.

- Add /location/educational/school_level route to query enrollments per school level;
- Add basic test case for the route. For now, it only checks if the format of the response is the expected one.
