    [N->O] Fix wrong database connection for cell0 during upgrade.

    During upgrade the cell0 database has the connection pointing to

       mysql+pymysql://nova:c2cdagE8PyAbnpers3AD88Hge@10.0.0.19/nova_cell0?bind_address=10.0.0.20

    where 10.0.0.20 was the ip of the bootstrap node. This makes the
    nova-api fails on 2/3 node at the end of the
    major-upgrade-composable-steps.yaml step.

    We do have the right value in the hiera database so make sure we use
    it for cell0 creation and not the nova.conf file which hasn't been
    updated yet.
