Install and configure needed kernel modules
CRIU needs to load the netlink_diag kernel modules in order for live-migration to work. In xenial the kernel module is located in linux-image-extra-`uname -r` debian package. However in yakkety and newer kernels its found in the regular linux kernel package. So install the needed debian packages and modprobe the module.
