prost_build::Config should be re-exported in tonic_build

[BaxHugh]

Feature Request

Crates

tonic-build

Motivation

tonic_build::Builder::compile_with_config takes a prost_build::Config as an argument, which requires the additional dependency of prost-build.

Since tonic_build already re-exports prost::{compile_fds, compile_protos, configure, Builder}, I think this compile_with_config should be callable without prost-build as a separate dependency

(I need to use compile_with_config, so that I can enable_type_names.)

Proposal

I propose we additionally re-export prost_build::Config and update the documentation here to include an example of using compile_with_config.

I'll be happy to create the PR, but first want to get feedback.

Alternatives

¯_(ツ)_/¯
