Release v1.28.0

This is the 1.28.0 release (galactic) of gRPC Core.

Please see the notes for the previous releases here: https://github.com/grpc/grpc/releases. Please consult https://grpc.io/ for all information regarding this product.

This release contains refinements, improvements, and bug fixes, with highlights listed below.

Core

• feat: add x-goog-user-project header from quota_project_id field. (#21324)

• Treat an empty http_proxy mean "Don't use proxy" and skip parsing it. (#21632)

C++

• This release adds an experimental client side implementation of xDSv2 APIs.
