Add a common method "get_shmem_regions":
This method get <IVSHMEM_REGION> and extracts the region size, region
position in xml and and vm ids which share this regions. Returns a
dictionary:
{'vm_id':{'region_name':{'id': region position,'size': region size,}}}
Add vm type checking methods:
is_pre_launched_vm, is_post_launched_vm and is_sos_vm.
