Sentry.io tracing implementation

[chrisparton1991]

Hi, Is there any prior art for integrating Sentry.io into Micronaut?

The Logback integration provided by Sentry allows for error reporting (which is great), but other tracing features require scope to be propagated between threads (I'm executing controller methods on the IO pool).

I imagine this would be a new implementation in micronaut-tracing alongside Jaeger and Zipkin.

If/when I've got time I'll try to get something basic working, but if anyone else has walked this path I'd love to hear from you!

Thanks :)

P.S. there's https://github.com/akyong/micronaut-sentry, but that's just the basic error handling described above. There's also some talk at https://gitter.im/micronautfw/questions?at=5fb4252df2fd4f60fc7d1d63, but only for initialising the Sentry SDK.
