The backup procedure on ubuntu does not work. Tried zed with the same problem
**Environment**:
* OS Ubuntu 22.04
* Kolla-Ansible version stable/zed
* globals.yml
enable_proxysql: "yes"
enable_mariabackup: "yes"
Running kolla-ansible -i /etc/kolla/inventory mariadb_backup
output is:

Password for user backup_shard_0 is not correct
ctrl-01:~# cat /etc/kolla/proxysql/users/mariadb.yaml
mysql_users:
- username: "root_shard_0"
password: "cGwdsSKM42857jQ8JOfhywbFq3LfkvT6LQBqLVcg"
default_hostgroup: 0
transaction_persistent: 1
active: 1
- username: "backup_shard_0"
password: "cGwdsSKM42857jQ8JOfhywbFq3LfkvT6LQBqLVcg"
default_hostgroup: 0
transaction_persistent: 1
active: 1
The password is taken from database_password, but should be taken from mariadb_backup_database_password
Was proposed to fix this misunderstanding https://review.opendev.org/c/openstack/kolla-ansible/+/900979
