Solr shard in response inaccurate / misleading

[sashakames]

"esgf-data-node-solr-query:8983/solr/datasets" is listed in the response from an API, but Solr is not being used. This is minor but could lead to confusion regarding the provenance of the information. Either leave blank or better yet replace with the UUID of the Globus Index.

This was mean to mimic the response from esg-search so that there was no way clients could tell the difference. Do we want to break that here?
