Clickhouse via MySQL protocol

I would like to contribute an improevemnt for the clickhouse module but I am unsure how to package it.

Clickhouse supports 3 ways of connecting:

• JDBC (basically only a wrapper around HTTP)
• Native protocol (CLI only)
• HTTP
• MySQL protocol
• PostgreSQL protocol

The current module supports:

• JDBC (basically only a wrapper around HTTP)

I'd like to provide a PR supporting MySQL (already got it working) and maybe even PostgreSQL but I am unsure how to package this. The JdbcDatabaseContainer is tied to a specific driver (the one from yandex). Would you rather have individual containers for each one? have a highly configurable container covering all areas? Any example fdrom an existing module that comes to mind?

Cheers, Jochen
