[kata-dev] Early access virtio-fs for Kata

Nice work folks! I'm looking forward to seeing it as the default kata
storage solution some day.

Also I'm wondering if there is interest in merging it in kata's qemu repo
(which is mainly qemu-lite and is the default hypervisor shipped by kata
packages). That would mean much wider user exposure. Of course it also
depends on how stable we think virtio-fs 1.0 is. Anyway, NEMU is already a
great step forward.

Cheers,
Tao
