feat(CI): Release Azure image to Gallery
- .raw image is downloaded from provided AWS S3 Object URL - .vhd image is downloaded from provided Azure blob URL - the tools/azure_uploader.sh script is used to convert the image into .vhd (if .raw provided), and then release to Gallery - the script releases to the 'almalinux_ci' private, or 'almalinux' community gallery (if "The Gallery is public" selected) - release is notified to Mattermost channel
