This commit introduces the ability to configure an external database for storing events. The configuration can be done via environment variables, allowing the use of different types of databases such as MongoDB, PostgreSQL, or MySQL.

By default, all events are stored in a local in-memory storage. However, with this update, users can now opt to use an external database by setting the PERSISTENCE_DRIVER environment variable to database or mongodb and providing the necessary database connection details.

Database

PERSISTENCE_DRIVER=database
DB_DRIVER=pgsql # mysql, pgsql
DB_DATABASE=buggregator
DB_HOST=127.0.0.1
DB_PORT=5432
DB_USERNAME=homestead
DB_PASSWORD=secret

MongoDB

PERSISTENCE_DRIVER=mongodb
MONGODB_CONNECTION=mongodb:https://127.0.0.1:27017
MONGODB_DATABASE=buggregator

This enhancement provides more flexibility in terms of data persistence and storage options for events."
