Allow requesting a mariadb set-up to replicate another mariadb: - bootstrap-url: bootstrap from a statically served backup file - primary-url: replicate from a primary mariadb This happens in mariadb first initialization, when no data exists yet. That way existing data in a non-replicating mariadb cannot be deleted by setting the replication parameters after the fact. A promise checks that the state (replica / primary, replication source) of the running mariadb matches the requested state; but if it doesn't, the mariadb will not automatically converge without human intervention if ~/srv/mariadb data directory already exists, to avoid deleting data.
