In a new microversion, 1.12, include project_id and user_id in the
output of GET /allocations/{consumer_uuid} and add JSON schema
to enable PUT to /allocations/{consumer_uuid} using the same dict-based
format for request body that is used in the GET response. In later
commits a similar format will be used in POST /allocations. This
symmetry is general good form and also will make client code a little
easier.
Since GET /allocation_candiates includes objects which are capable
of being PUT to /allocations/{consumer_uuid}, its response body has
been updated as well, to change the 'allocation_requests' object
to use the dict-based format.
Internally to handlers/allocation.py the same method (_set_allocations)
is used for every microversion. Any previous data structure is
transformed into the dict-ish form. This means that pre-existing tests
(like allocation-bad-class.yaml) continue to exercise the problems it
was made for, but needs to be pinned to an older microversion, rather than
being latest.
Info about these changes is added to placement-api-ref,
rest_api_version_history and a reno.
