First pass on Observability support

How does relate to spring cloud sleuth?

[spencergibb]

Only indirectly as the new micrometer functionality replaces sleuth

[proteintogo]

I added the following dependency micrometer-tracing-bridge-brave along with spring-cloud-starter-gateway:

Configured the logging.pattern.level=%clr(%5p) %clr([TraceId=%X{traceId:-},SpanId=%X{spanId:-}]){green}

But when I log any message, no traceId/SpanId is completed. Should I do any additional step/configuration ?

Check this doc https://micrometer.io/docs/observation#instrumentation_of_reactive_libraries and if you don't want to do anything manually you have to wait until we patch reactor and boot to support this out of the box

@marcingrzejszczak I added;

Hooks.enableAutomaticContextPropagation();

but traceIds do not appear in the logs. I created a sample project to reproduce. Any help would be much appreciated, thanks in advance.
