quick try to make #3232 work

Arf.. looks like this is causing issues; google/gnostic@896953e.

And more errors currently;

/go/src/github.com/docker/cli/vendor/go.opentelemetry.io/proto/otlp/trace/v1/trace.pb.go:25:6: could not import go.opentelemetry.io/proto/otlp/common/v1 
/go/src/github.com/docker/cli/vendor/go.opentelemetry.io/proto/otlp/common/v1/common.pb.go:40:17: ProtoPackageIsVersion4 not declared by package proto)

Those should be because the version that was specified is too old (needs v1.4 or above; golang/protobuf@ae97035)

[thaJeztah]

oh! this one is weird

/go/src/github.com/docker/cli/cli/command/image/build_buildkit.go:403:9: v declared but not used 

also

/go/src/github.com/docker/cli/vendor/go.opentelemetry.io/proto/otlp/collector/trace/v1/trace_service.pb.gw.go:164:132:

Last one; runtime refers to github.com/grpc-ecosystem/grpc-gateway/runtime. Probably needs an update. https://github.com/moby/buildkit/blob/v0.9.0/vendor/modules.txt#L280 shows:

# github.com/grpc-ecosystem/grpc-gateway v1.16.0
github.com/grpc-ecosystem/grpc-gateway/internal
github.com/grpc-ecosystem/grpc-gateway/runtime
github.com/grpc-ecosystem/grpc-gateway/utilities

and

# github.com/grpc-ecosystem/go-grpc-middleware v1.2.0
github.com/grpc-ecosystem/go-grpc-middleware

Getting closer;

We need to check if we need the fork for this; https://github.com/moby/buildkit/blob/v0.9.0/go.mod#L79-L83

[crazy-max]

Yes indeed I didn't take these ones into account. Hopefully should be fixed upstream soon:

• otelhttp: get tracer from current context if not set in constructor open-telemetry/opentelemetry-go-contrib#873
• otelhttptrace: get tracer from request if available open-telemetry/opentelemetry-go-contrib#874
• otelhttp: add WithClientTrace to connect with otelhttptrace  open-telemetry/opentelemetry-go-contrib#875

[thaJeztah]

Added a commit to use that fork
