Elasticsearch update

The genesys-catalog project introduced new approach to indexing with Elasticsearch.

Bring Elasticsearch components into this project and migrate methods implemented in Genesys to the new base code from the Catalog.

You can mass-load accession passport data into your Genesys database using Anno (Genesys uploader) and data from https://eurisco.ipk-gatersleben.de/apex/EURISCO_WEB.download_file?p_id=67 found on https://eurisco.ipk-gatersleben.de/apex/f?p=103:25:::NO::: (right hand side "Download full dataset").

Note that the default OAuth clientId and secret are logged to the console when Genesys starts up with a blank database and uses auto.createContent=true -- also echoed on in the log.
