Describe the feature.

Users could be informed that certain versions of components/assemblies are:

• no longer supported
• that a new minor/path is available
• that a new major is available
• "old"

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.
