RFS: golang-github-grpc-ecosystem-grpc-opentracing

[Tong Sun <suntong001@users.sourceforge.net>]

Dear Go team,

I'm looking for a sponsor for the package
"golang-github-grpc-ecosystem-grpc-opentracing" (#953324).

This package is a prerequisite for the upcoming package of
github.com/google/go-containerregistry

The package is at:
  https://salsa.debian.org/go-team/packages/golang-github-grpc-ecosystem-grpc-opentracing

The package was tested on both gbp and sbuild. It's also lintian-clean.

Please consider to review and upload it. Any kind of suggestions are
appreciated.

Thank you!
