[6.17.z] Make container and flatpak hosts ipv6 aware

[Satellite-QE]

Cherrypick of PR: #17788

Problem Statement

Several tests fail in host setup in IPv6 pipeline since they are unaware of IPV context and spawn on IPv4 infra.

pytest_fixtures/core/contenthosts.py:235: in module_flatpak_contenthost
    with Broker(**host_conf(request), host_class=ContentHost) as host:
    ...
    sock.connect((host, port))
E   socket.gaierror: [Errno -5] No address associated with hostname

Solution

Deploy them properly per IPV settings.
