s390x-bbw1 host was upgraded from EOL 2004 to 2404

Will handle file changes manually on both environments.
Builds are scheduled based on host load and the data is retrieved from Zabbix based on the following mapping `private_config["private"]["worker_name_mapping"][worker_prefix]`
s390x master restart is required.
