Description

When you are behind a corporate proxy, DSpot amplification, triggered by python publisher.py -d /queue/Dpipeline pipelineid, fails because it can't download dependencies from Maven repositories, so it is needed to pass proxy configuration in some way.

Steps to reproduce

Having setup everything according to PR #840, the execution ends with following error stacktrace:
