Keep existing data when moving to containerized MariaDB
We used named Docker volume for MariaDB storage, which meant that when moving from BM to containerized wit MariaDB, we lost data and reinitialized the storage from scratch. With this commit we keep the data by mounting the original data into the container. We also need to make sure that file ownership is correct according to the MariaDB container image used, and that Kolla bootstrap mechanisms aren't retriggered, as they aren't idempotent.
