While parsing each parameter for getting the list of option/value, we
check if the value is a list separated between brackets. If that's the
case, we reconstruct the list so that it can be parsed afterwards, even
though it uses commas for separating each value.

This new option provides a new way to describe the memory associated
with a NUMA node. This is the first step before we can remove the
'guest_numa_node' option from the --memory-zone parameter.

By introducing 'distances' option, we let the user describe a list of
destination NUMA nodes with their associated distances compared to the
current node (defined through 'id').

Through this new parameter, we give users the opportunity to specify a
set of CPUs attached to a NUMA node that has been previously created
from the --memory-zone parameter.
This parameter will be extended in the future to describe the distance
between multiple nodes.
For instance, if a user wants to attach CPUs 0, 1, 2 and 6 to a NUMA
node, here are two different ways of doing so:
Either
./cloud-hypervisor ... --numa id=0,cpus=0-2:6
Or
./cloud-hypervisor ... --numa id=0,cpus=0:1:2:6

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.
