Adding automatic nightly release builds

- Restructured linux repo directory structure to include Stable and Nightly releases
- Reworked Earthfile to pass IS_NIGHTLY boolean to package build scripts for use in
file names
- Added nightly pipeline to CICD config yaml. Pipeline is triggered by IS_NIGHTLY
variable
- Two distribution scripts now exist, one for Stable and one for Nightly
- Reworked RPM build spec files to create appropriate file names
- Reworked debian release generation scripts
- RPM repo directory structure is prepped for arm64 builds
- Switched from scp to rsync for moving the completed repo from ochestration
to repo server
- Created schedule in Gitlab UI to trigger nightly release at 2300 Central Time
