In #421 and #355 the queue was separated to allow an actinia worker to process the job independantely from the instance which received the job.

There are no tests for this yet as a different config is needed and a mechanism how to start the worker.
Tests would be needed for queue_type = per_job and queue_type = per_user.

It is also necessary to get rid of all the config overwrites inside the tests, e.g. for resource storage or redis database.
