--- BEGIN ISSUE ---
Haystack rest endpoint response serializer does not include short_id
**Description of the bug**
The Haystack REST endpoint for complex solr searches does not include the short_id into the response serializer. This is a critical piece of information for users of this endpoint.   

Steps to reproduce the bug:
https://github.com/hydroshare/hydroshare/blob/d3bd1737a0179eac74cd68926b3b79b80894410e/hs_rest_api/discovery.py#L12

**Expected behavior**
I expect resource ids to be included with search results so I can retrieve resources.
