ExtraHostFileEntries only works for -ONE- entry, not more than one

[Cédric Jeanneret]

(Discovered on Red Hat BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1815218)

Basically, when we pass a list of entries in ExtraHostFileEntries, it get written as a single, one-liner in the /etc/hosts file.

This is a regression due to the introduction of tripleo_ansible "tripleo_hosts_entries" role.

The following patch corrects the issue:

    Rework how we push the content in the file

    Since we allow to pass lists, we can't just use |join('').

    In addition, using the multi-line support in YAML via the "|" creates
    some issues when we want to use |join('\n'): it gets escaped, meaning we
    end with a one-line content with some \n entries.

    The present patch ensures that:
    - generated content is still pushed in a fact to not lose time
    - static content (lists) is properly treated and outputs correctly
