Use `cleanup-markdown` `prost_build` feature

[cortopy]

Feature Request

Crates

tonic-build

Motivation

I just saw the new feature in prost_build to clean up the markup of generated code using cleanup-markdown feature. This has been a problem for me for a long time because googleapis protobuf files are picked up in tests and fail. This would allow for easier test flows

Proposal

Enable cleanup-markdown feature of prost-build

Alternatives

Not that I know of as prost-build is a dependency of tonic-build, not direct from my project

[LucioFranco]

Good idea, we can add a new feature to tonic-build that just forwards that specific feature. I would accept a PR for this.

[cortopy]

thanks @LucioFranco I can do a PR but I didn't know enabling a future conditionally was possible with rust. Is there any doc I can read on how it could be done?

I believe the best spot to read about it is here https://doc.rust-lang.org/cargo/reference/features.html
