Based on https://github.com/rustls/rcgen/blob/main/rcgen/CHANGELOG.md, ring was made into an optional dependency with aws-lc-rs as an alternative choice. The create now requires either ring or aws-lc-rs to be specified as a feature (with ring as a default feature).
To be consistent with previous functionality, this PR uses ring.
