a5a29134ca vmm: Extend --numa parameter with NUMA node distances 
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').

42f963d6f2 main, vmm: Add new --numa parameter 
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

b69f6d4f6c vhost_user_net, vhost_user_block, option_parser: Remove vmm dependency 
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.
