*: bump gRPC dependencies (#5075)
* *: bump gRPC dependencies

This change updates the gRPC dependencies to more recent versions:

* github.com/gogo/protobuf => v1.2.0
* github.com/grpc-ecosystem/grpc-gateway => v1.6.3
* google.golang.org/grpc => v1.17.0

In addition scripts/genproto.sh leverages Go modules information instead of
hardcoding SHA1 commits. This ensures that the code is generated from
the exact same sources.
