Roadmap for V1

[pavolloffay]

This issue outlines a short term roadmap for reaching supportable V1. The instrumentation scope focuses on server-side frameworks and Spring Web. The server-side frameworks were chosen because this is where HT agent provides value for blocking and additional data capture.

Instrumentation:

• Spring Webflux instrumentation (via netty) Netty instrumentation is not closing spans when used with Spring webflux #206
• Micronaut instrumentation (via netty) Test netty instrumentation on Micronaut #207
• Netty client instrumentation Add Netty client payload and headers capture #215
• Spring web - Rest template Add payload and headers capture to Spring RestTemplate #214
• Struts Add payload and headers capture for Struts #218
• Remove wrapping from servlet instrumentation Remove wrapping from servlet instrumentation  #222

Testing:

• Abstract server tests Define abstract HTTP server test #99
• Abstract client tests Define abstract HTTP client tests #98
• Smoke tests for servlet containers and make it pluggable Add more smoke test and framework how to add more tests #217
• OPA filter smoke/contract tests OPA filter smoke tests #157
• Run tests with Javaagent Run tests with javaagent #238

Issues:

• Test startup time and make sure HT agent does not drift from upstream Startup takes around 30s #212
• Config is being loaded twice Hypertrace config is being loaded twice #223

Agent core:

• Log to file Allow for the OTel Java agent to take in a file as the logs output destination #172
• HT agent size is 18 MB bigger than OTEL Investigate increased agent size #220

Apart from the issues listed here the V1 should include almost everything from #216.
