Current OSUS codebase is stuck on Centos 7 images and custom built rust using rustup.

We should be using Official Rust toolset and UBI8 containers to keep RPM dependencies updated.

Migration plan:

• Create a PR to OSUS codebase to add alternative Dockerfiles using rust-toolset and UBI8. See cincinnati-graph-data as an example
• Create a CI variant of tests to build via rust-toolset images
• Ensure that functionality hasn't been impacted
• Remove outdated images, switch to rust-toolset
