#5452 feat/Include drivers for Postgres and MySQL/MariaDB by default

Current docker image only includes the driver for SQLite.

I believe those of us running many instance of Hummingbot, or want a centralised db storage (for post-trade analytical purposes) would prefer logging trades in a different RDBMS such as PostgreSQL or MySQL/MariaDB. However, this means we would need to build the docker image ourselves every time a new release of Hummingbot is out, in order to work with a non-SQLite database.
