vmm: Add 'guest_numa_node' option to 'memory-zone'

Browse source 
With the introduction of this new option, the user will be able to
describe if a particular memory zone should belong to a specific NUMA
node from a guest perspective.

For instance, using '--memory-zone size=1G,guest_numa_node=2' would let
the user describe that a memory zone of 1G in the guest should be
exposed as being associated with the NUMA node 2.
