dracut: add 'dracut_NM_NFS_remote_rootfs_connection[_var2]' tests
Add tests, that NM is able to use persitent profiles saved on remote root. This seems to be problematic, if tested on interface used for NFS root (even if configured the same in initrd and remote), so another interface added (iscsi0), and it changes from DHCP (initrd kernel argument) to manual IPv4 (profile saved in remote root).
