Sleuth 3.1.11 was released and that fixed flux eureka discovery as well moved off deprecated functions that made it impossible to update to Brave 6.0.

This does a few things:

• resurrects webflux5-sleuth adding the same eureka configuration as webmvc5-sleuth
• un-pins the brave version in both sleuth examples (so it now uses Brave 6.0)
• makes our CI enforce eureka tests, to avoid any future drift breaking any of our examples.
  • we need this to protect the time of our maintainers, due to lack of regularly run integration tests anywhere else.
• refactors also the kafka tests to reduce duplication, despite Extend service with depends_on should work  docker/compose#7916

Note: Sleuth is still pinned to reporter 2.x as it includes auto-configuration of its own senders which rely on 2.x signatures. However, Brave no longer cares about reporter versions, and this repo is mostly about brave.

While automatically tested now (and yeah I verified in the logs it is), I also manually tested all the eureka-enabled examples and pasted screenshot of best request in 6 below:

armeria (netty) 2.7ms

webflux5-sleuth (netty) 4.1ms

webmvc5-sleuth (servlet) 3.4ms

Nice job as always, armeria (ack it is cheating as armeria has effectively zero abstraction cost :p)
