ansible_default_ipv4.address cant detect public ip for build-scaleway-ubuntu1604-armv7-1 and -2

[Haroon-Khel]

Ansible isnt able to detect the public ip address for the machines build-scaleway-ubuntu1604-armv7-1 and -2.

On other machines, the ansible variable ansible_default_ipv4.address is equal to the public/external ip address, but for these two machines, it is equal to the private ip adresses

On -1 for example
"ansible_default_ipv4.address: 10.1.14.2",

This causes hosts_file tasks in the adopt_etc role to enter this address in /etc/hosts, causing an improper entry, causing errors such as #1907

ansible_ssh_host is another ansible variable for a machine's public ip. Could use this instead of ansible_default_ipv4.address, but would like to better understand why ansible isnt able to detect the public ip using ansible_default_ipv4.address

build and test-alibaba-ubuntu1804-armv8-1 and build-scaleway-ubuntu1604-x64-1 are experiencing the same issue
