Make create detail optionally more verbose

Problem/Motivation

Currently the agents only shows diff information on edit, on create it only shows the id of the configurations it wrote. We should have the opportunity to be able to see a whole dumpt of the configurations that got written.

Proposed resolution

Add a settings (for each agent?) how to deal with verbose output.
Make sure to write the verbose output if wanted.

Remaining tasks

User interface changes

API changes

Data model changes
