Public bug reported:

aggregate-create and aggregate-details return inconsistent result.

The results the 2 API aggregate-create and aggregate-details return:
1.create(nova aggregate-create agg-1 zone-1):
{"availability_zone": "zone-1", "created_at": "2015-11-26T06:56:17.000000", "deleted": false, "deleted_at": null, "id": 18, "name": "agg-1", "updated_at": null}

2.get(nova aggregate-details agg-1):
{"availability_zone": "zone-1", "created_at": "2015-11-26T06:56:17.000000", "deleted": false, "deleted_at": null, "hosts": [], "id": 18, "metadata": {"availability_zone": "zone-1"}, "name": "agg-1", "updated_at": null}

The result aggregate-create API returns does not contain attributes
'hosts' and 'metadata'.

When we call the following two API[1] in horizon, in order to make the
results consistent, we must call the API 'aggregates.get' again after
'aggregates.create'.

I think aggregates.create API should return result similar to
aggregates.get API (that is to contain attributes 'hosts' and
'metadata').
