    [placement] reorder middleware to correct logging context
    
    The initial bug was that the initial 'Starting' log provided by
    requestlog had a different request id from the rest of the log
    messages for the same request. The initial assumption was that this
    was because a request id was not initially available, causing one
    to be generated for the first log entry that later was replaced
    by the request id middleware.
    
    In the process of debugging that it became clear that the id was
    in fact the request id of the previous request because the context
    was being reused under the covers in oslo_log and olso_context.
    
    Therefore the auth, context and request id middlewares are now
    changed to be active in the middleware stack before the request log
    middleware. The unfortunate side effect of this is that the Starting
    message and final request logging is no longer actually bounding the
    full request: it misses three critical middlewares.

Title:
  placement api log entries have mismatched request ids

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  The placement (v 1.0) API's service logs get confused about request
  id. The following is one request:

  ```
  2016-09-22 10:54:54.372 22919 DEBUG nova.api.openstack.placement.requestlog [req-93669abf-57c5-4415-a734-1affc816a9ae admin admin] Starting request: 10.0.2.15 "GET /placement/resource_providers/fastidious" __call__ /opt/stack/nova/nova/api/openstack/placement/requestlog.py:36
  2016-09-22 10:54:54.414 22919 INFO nova.api.openstack.placement.requestlog [req-7312f440-2c66-4483-a514-eaf3602b50e6 admin admin] 10.0.2.15 "GET /placement/resource_providers/fastidious" status: 404 len: 80
  ```

  This is probably because the request id middleware is not being called
  first.
