  - Merge "[SDNC] Use common secret template in ansible-server"
  - [SDNC] Use common secret template in ansible-server

    Whole SDNC strongly depends on the assumption that it is using a
    common mariadb-galera instance and that root password is secret
    password. Also user and password to sdnc DB is hardcoded.

    Let's start working on removing this assumption and component by
    component add support for local and shared mariadb instance without
    hardcoding any passwords to the database.

    In this patch all passwords are still hardcoded in the helm chart to
    not break other parts of SDNC. Those values will be removed in a final patch.
