Add RPM registry (#23380)

Fixes #20751

This PR adds a RPM package registry. You can follow [this
tutorial](https://opensource.com/article/18/9/how-build-rpm-packages) to
build a *.rpm package for testing.

This functionality is similar to the Debian registry (#22854) and
therefore shares some methods. I marked this PR as blocked because it
should be merged after #22854.
