Implement an audit log for tracking user actions in ARIS

We have often requests from customers to check who did certain action in ARIS (e.g. who uploaded and activated modset/configset etc). Such information is partly covered by user statistics, but is incomplete.

It will be good to have something as an audit log where we can track the user who did certain action in teh system. The importance of this is due to the fact that there are multiple teams involved in managing customer instance (MaSe, PS, Customer team) and sometimes we are not able to track who did the latest changes to the system.
