c8s has an updated rust that supports building crates targeting the 2021 edition of the language. Build below 0.5.0 against this as that simplifies the release process (no need to keep patching even more code to support building against the 2018 edition), and we can rebuild for epel8 once RHEL 8.6 is released with the updated Rust.
