Pull request #1433: Upgrade elasticsearch version 7
Merge in CATS/clowder from upgrade-elasticsearch-version-7 to 2.0-work-in-progress
* commit '3930461967d4a550d4cf9bbd6e95eeabe17c0594': (21 commits)
Default port for elasticsearch from 9300 to 9200 since with the upgraded to v7 we now use the HTTP port to connect. Changed default Elasticsearch cluster name to `clowder` since that is what we use in the docker compose. Rolled back change to the name of the elasticsearch volume.
Print exception if there is an unknown error connecting to Elasticsearch.
