[dependabot-preview[bot]]

Bumps google.golang.org/grpc from 1.27.1 to 1.28.0.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.28.0

New Features

• This release adds an experimental client side implementation of xDSv2 APIs. This allows a gRPC client written in Go to receive configuration from an xDSv2 API compatible server and use that configuration to load balance RPCs. In this release, only the virtual host matching and cluster route action is supported. More features will be added in future.
• grpclb: support explicit fallback signal (#3351)
• interceptor: new APIs for chaining server interceptors. (#3336)
  • Special Thanks: @tukeJonny
