Backup playbook freezes at "Create etcd snapshot"

[Bernardo Decco de Siqueira]

Brief Description

Have a fully deployed setup.
Playing with window size of the terminal then running backup.yml may freeze the ansible task.

Initial investigation showed etcdctl had a bad formated argument for endpoint. Instead of a full IPv4 (192.168.206.1) it had a partial (192.168.).
Ip is determined by this command : `system addrpool-list | awk '/cluster-host-subnet/{print$14}'`.

I was able to reproduce the error using a 1680x1050 display.
After zoom out the terminal the create etcd step passed.
To fix this bug we need to add the --nowrap to system addrpool-list at the task 'Get etcd endpoints' on /usr/share/ansible/stx-ansible/playbooks/roles/backup/backup-system/tasks/main.yml

WRCP version 21.12

screening: very specific issue related to the terminal settings when running the B&R; would be nice to fix, but will not hold up any release
