Title:
  Sending empty allocations list on a PUT /allocations/{consumer_uuid}
  results in 500

Status in OpenStack Compute (nova):
  In Progress
Status in OpenStack Compute (nova) ocata series:
  Confirmed

Bug description:
  If you send an empty allocation list to the placement server:

  - name: put an allocation empty list
    PUT: /allocations/599ffd2d-526a-4b2e-8683-f13ad25f9958
    request_headers:
        content-type: application/json
    data:
        allocations: []

  You'll get a 500 response because of an Index error when consumer_id =
  allocs[0].consumer_id.

  Instead we should never reach this code. There should either be a
  schema violation, because we should have at least one allocation, or
  if we're willing to accept an empty list and do nothing, w should skip
  the call to the database.
