Use the new logic from c/common to create the hosts file. This will help to better allign the hosts files between buildah and podman. Also this fixes several bugs: - remove host entries when container is stopped and has a netNsCtr - add entries for containers in a pod - do not duplicate entries in the hosts file - use the correct slirp ip when an userns is used Features: - configure host.containers.internal entry in containers.conf - configure base hosts file in containers.conf Fixes #12003 Fixes #13224 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
