[Limitation] MariaDBDatabase always registers "databaseName" as the DB user for the schema

[gibizer]

mariadb-operator/templates/database.sh

Line 4 in 597b259

mysql -h {{.DatabaseHostname}} -u {{.DatabaseAdminUsername}} -P 3306 -e "CREATE DATABASE IF NOT EXISTS {{.DatabaseName}}; GRANT ALL PRIVILEGES ON {{.DatabaseName}}.* TO '{{.DatabaseName}}'@'localhost' IDENTIFIED BY '$DatabasePassword';GRANT ALL PRIVILEGES ON {{.DatabaseName}}.* TO '{{.DatabaseName}}'@'%' IDENTIFIED BY '$DatabasePassword';"

While this is OK for the Demo usage. I opened this issue to make the limitation visible.

Probably this needs to be fixed for adoption where we cannot influence the username of the DBs.
