Repair Zipkin Micrometer Tracing

[arey]

It seems that since the upgrade to Spring Cloud 2022.0, the OpenZipkin server is no longer receiving the traces.
We should use Micrometer to trace your Spring Boot app: https://springbootlearning.medium.com/using-micrometer-to-trace-your-spring-boot-app-1fe6ff9982ae

Can I work on this issue?

Yes @MarianConstantinMarica you can work on this issue. Thank you for the proposal.

Ah, is this why I don't see any traces? I just downloaded the latest master and ran using scripts/run_all.sh and expected traces to magically appear at http://localhost:9411/zipkin/ but nothing appears. Any idea what the last working branch was?

@dgriffiths-undo you may try the previous version: https://github.com/spring-petclinic/spring-petclinic-microservices/tree/v2.6.7

[dgriffiths-undo]

Ok that works, thanks!
