@cedricziel - It looks like CI is failing. Seems gRPC/boringssl build is breaking with the newer gcc compiler. otel-cpp is still not tested on the ubuntu 22.04. Looks like gRPC needs to be upgraded.
fyi - @tobiasstadler is approver for Nginx.

Could we support ubuntu 22.04 in otel-cpp for now?

Yes, we should do it once gRPC gets upgraded. And also, would be good to add support matrix for OTLP-gRPC for various compiler/package versions.

There are some warnings that will break the compiling when using new gcc and clang.I have some patches for the compiling problems in another project, it may be helpful.
