* Use `quay.io/dghubble/protoc` as the standard codegen environment across projects. Pin a version (v3.10.1) * Generated code is now automatically ignored by golint based on the comment header, which will simplify linting * Upgrade protobuf from 2bba0603135d to v1.3.2 * Upgrade grpc from v1.2.1 to v1.25.1 * Remove `get-protoc` and `codegen` scripts
