Create a raw file and bind mount it to use it as disk is not needed,
instead a the raw file can be created at the jail path and use it directly
as disk, if a new container is added the real disk/device can be bind mounted
in the raw file.

The netlink dep needs to be updated to get logic for the tuntap
link. It is fixing a bug that uses a generic link instead.
This also requires the golang/x/sys package to be updated
for the IFLA_* constraints.

Kata support several hypervisor and not all hypervisor support the

firecracker only support hybrid vsocks, hence sockets generations should be
hypervisor specific
