XenAPI get_all_bw_usage using name-label to ingore control domain

[Rick Harris]

This method works (for now), but the vm_record contains an attribute called 'is_control_domain' which would be better to use for this purpose.

if name.startswith('Control domain'):
  continue

should be

if vm_rec['is_control_domain']:
  continue

While we're at it, we probably want to ignore template VMs as well so, it probably should be:

# see VMHelper.list_vms
if vm_rec['is_control_domain'] or vm_rec['is_a_template']:
  continue
