DBController refactoring (#1228)

* Moves transform to MongoTransform

- Adds ACL query injection in MongoTransform

* Removes adaptiveCollection from DatabaseController

- All collections manipulations are now handled by a DBController
- Adds optional flags to configure an unsafe databaseController for direct
  access
- Adds ability to configure RestWrite with multiple writes
- Moves some transfirmations to MongoTransform as they output specific code

* Renames Unsafe to WithoutValidation
