Before this patch, VM diagnostics response was just a
'blob' of data returned by each hypervisor. New API
version makes diagnostics response standardized.
New response has a set of fields which each hypervisor
will try to fill. If hypervisor unable to provide a
specific field then this field will be reported as 'None'.
