  - [NBI] Don't hardcode mariadb-galera password

    Let's use common secret template to generate user credentials for NBI
    DB and depend on mariadb-galera to generate secure enough root
    password.

    BTW.
    Don't be surprised for now mariadb-galera has a hardcoded root
    password but as soon as we move all charts that use it to common
    secret template it will be auto generated.
