network dis-/connect: update /etc/hosts
When we connect or disconnect from a network we also have to update /etc/hosts to ensure we only have valid entries in there. This also fixes problems with docker-compose since this makes use of network connect/disconnect. Fixes #12533 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
