Refactory files

Detail

• The server is separated from the application. Using server.js for init the server and using app.js for create the application. The startup is server.js
• Create single file for call .env variables on server. src/server/config/variables.js
• Separate models and schemas. Now the schema is placed on the src/server/schema and the model on src/server/models. The model call to schema.
