* Move proto to OTLP exporter
* Update OTLP exporter import of proto
* Use gogo protobuf
To stop using the deprecated github.com/golang/protobuf and match what
the collector is doing, switch to generating OTLP with the
github.com/gogo/protobuf/proto instead of
github.com/golang/protobuf/proto.
* Clean dependencies
Remove all protobuf dependencies from otel package and all of its
dependencies.
* Update CHANGELOG
* Clean OTLP exporter go mod
Remove submodule beforehand to avoid unneeded direct dependencies.
* Use default ref for GitHub workflow
* Update path that triggers proto gen action
* Correct license-check exclusion for OTLP
* Update commented location of the OTLP and code
* Clean stale indirect dependency requirements
In the recent changes to isolate the main `otel` package there were many
indirect dependencies of the package that were removed, however, the
go.mod was not automatically cleaned of these. This removes those (and
similar ones in the otel-collector example and otel exporter) and prunes
the go.sum files accordingly.
* Run in a clean system to reproduce build
* Make opentracing bridge into own Go module
* Update dependabot config
* Clean dependencies of project
Now the bridge is a module, clean all upstream modules that no longer
implicitly depend on it.
* Update Changelog
* go mod tidy
