Enrich actionjournal entry for middleware configuration

[volllly]

#312 (comment)

Background

We changed this object we're logging to only log things we explicitly put in as to not log anything confidential by accident (e.g. if a confidential field is added later on in the config it would not be readacted in older queue versions).

Feature

We should add more items to this entry like:

• Queue Version
• Assembly Information
• ??
