dc-interface with less provenance pushes

Full Changelog: 7.0.0...7.1.0

dc-interface with provenance on each call

This SDK sends the provenance name and version, that is the name and version of the data collector with each call. It is mainly useful for logging, to find the culprit of errors, or to generate statistics in our ELK stack.

In addition, it no longer pushes and retrieves the provenance UUID from the database. This is now just done once per data collector execution and stored locally. This should reduce the DB calls during data pushes.
