Where can the grpc dependent files be found or is there any other way to implement them

[CloudWise-Lukemiao]

We are implementing a new database. We want to access the Prometheus data into this database. I checked the data and need to use remote.proto and types.proto to generate grpc files. But I found that these two files rely on gogoproto / gogo.proto, and I can't find this file. Where is this file or is there any other jar directly used?

Gogo proto is an alternate protobuf implementation we use: https://github.com/gogo/protobuf

More recently there are suggestions to use the Buf registry to generate; see #11908
