* Create routes /enrollment/gender and /enrollment/ethnic_group
* Add gender and ethnic_group to enrollment params in RQF

Route /api/v1/simulation/time exists and works with parameter max_time

* Example route: `/api/v1/simulation/time?max_time=10`
* Return value: {"result": [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]}

If no value is specified in max_time, an error is returned

SQL now is using new schema

- Mount route under '/api/v1/enrollment/location'
- It should list the location names for enrollments and school classes
- The reponse format is a lista of objects with each object having a location_id (CEBES014T1) and a description

- 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.

Change SQL queries in the following routes:

* city
* state
* region
* school
* enrollment

Also, change tests to reflect the new schema where appropriate. Specially in the case of cities, the primary key now becomes pk_cod_ibge (city IBGE code) and, therefore, any query that relies on the city id should use this value instead of the old primary key.

Aliases of fields that have different names were added to ensure compatibility with the UI of LDE.

Please refer to the database repository in order to understand how the current schema works. The corresponding ER diagram can be located there.

Sanitize the location in the result
