rpm-rs backend

[tarcieri]

rpm-rs is a pure Rust library for building and parsing RPMs:

https://github.com/Richterrettich/rpm-rs

It includes support for much of the functionality in (lib)rpmbuild, including producing signed RPMs.

Unfortunately cargo-rpm is presently largely driven by .spec files, so supporting it would be a pretty major change.

It might be nice to support building RPMs without a spec file by using rpm-rs (i.e. via Cargo metadata alone), while retaining the current rpmbuild-based backend as well.

I started working on this. This is also the reason why I wanted to add the "build hooks".

@musikid aah, interesting. I think it'd be cool if you could make the rpmbuild invocation into a "build hook"
