Title:
  metadata server update_all expects body but doesn't get it passed to
  it

Status in OpenStack Compute (Nova):
  Confirmed
Status in Tempest:
  New

Bug description:
  This recently started showing up in n-api. Seems like mishandling of invalid client args from a negative test in tempest.
  Example: http://logs.openstack.org/03/52803/3/check/check-tempest-devstack-vm-postgres-full/354d7a3/logs/screen-n-api.txt.gz
