 Title: #574: cache_req: Don't force a fqname for files provider output
Action: opened

PR body:
"""
    As we're enforcing the output of files provider to be fully-qualified we
    can face some weirdness when using domain_resolution_order as:
    [user@implicit_files@machine]$

    This is not only not coherent but also causes issues when the local
    user, which is managed by the files provider, tries to do a `sudo su`.
    In this scenario, the user is asked by the password (doesn't matter
    whether it's part of sudoers) and never is allowed to log-in.

    In order to avoid the issues described above, let's just not force the
    output of the files provider to be fully-qualified.

    NOTE: I do not understand clearly why the issue with sudo happens.
