🚀 Feature: External Redis Database Secure Connection

Nadie ha tomado este issue todavía.

### 🔖 Feature description

Enable the option to use a secure connection to an external Redis Database, using -tls or rediss:// to connect to the database.
Right now is only possible to use a non-secure, as the codebase concatenates the connection info with redis:// instead of rediss:// wich is secure.

### 🎤 Pitch

Right now, based on the env vars and the code, appwrite only supports non-secure connections to Redis, so in order to connect to an external Redis Database the only way is to use a non-secure conection.

If we want to scale appwrite and we need to be able to use a centralized databse wich we can scale.

Comienza rastreando el código de conexión de Redis que lee las variables de entorno y actualmente concatena redis://. Comprueba cómo se representa la opción de conexión y, después, verifica que tanto -tls como rediss:// puedan conectarse a una base de datos Redis externa sin romper las conexiones no seguras.
