Update the common part in net_util.rs under vm-virtio to add mq
support, meanwhile enable mq for virtio-net device, vhost-user-net
device and vhost-user-net backend. Multiple threads will be created,
one thread will be responsible to handle one queue pair separately.
To gain the better performance, it requires to have the same amount
of vcpus as queue pair numbers defined for the net device, due to
the cpu affinity.
Multiple thread support is not added for vhost-user-net backend
currently, it will be added in future.

refactoring code for virtio-net device, vhost-user-net device
and backend to shrink the code size and improve readability
meanwhile.

Extend VhostUserBackend trait with protocol_features(), so device
backend implementations can freely define which protocol features they
want to support.

Clean up the error handling and ensure that where possible errors are
propagated. Make use of std::convert::From in order to translate error
types.

Simplify the check for the unusual situation where the memory is not
configured by using .ok_or() on the option to convert it to a result.
This cleans up a bunch of extra indentation.

Remove messages that are left over from the development of the project
that represent normal operation for the backend. This cleans up the
console output and improves performance.

Create vhost-user-net backend with Tap interface, to offload network
transaction from cloud-hypervisor. The goal is to provide flexibility
about the backend being in use, but also more security as it will allow
users to isolate the backend with different security profiles since it
will run as a dedicated process on the host.
