Solution: Startup task / healthcheck

A solution suggestion could be a startup task (log/check once at start) or a healthcheck (log/check at an interval).

It could async query for version info by fetching all versions for NServiceBus component(s) or if no outgoing connection is allowed to log a warning if the component age is for example 3 years.
