Overcloud password changed in FFU 16.2 --> 17.1 and FFU got stuck

Issue

The "openstack overcloud upgrade run..." command failed and galera cluster has at least one node broken.

Possible output from the command:
1.- FATAL | Create containers managed by Podman for /var/lib/tripleo-config/container-startup-config/step_2 | controller-0 | error={"changed": false, "msg": "Failed containers: mysql_wait_bundle"}
