feature: add ability to mount db contents in mariadb module #9
Description
The mariadb container offers this ability
Initializing the database contents
When a container is started for the first time, a new database with the specified name will be created and initialized with the provided configuration variables. Furthermore, it will execute files with extensions .sh, .sql, .sql.gz, .sql.xz and .sql.zst that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. .sh files without file execute permission are sourced rather than executed. You can easily populate your mariadb services by mounting a SQL dump into that directory and provide custom images with contributed data. SQL files will be imported by default to the database specified by the MARIADB_DATABASE variable.

We should support this in the mariadb module by allowing an extra argument point to the contents directory and them mounting it at /docker-entrypoint-initdb.d
