Comparation between this PR and #36:
They are all about the image disk operation, the difference is current PR is function reuse from Swiftloom, the PR36 is package reuse from azurelinux. current implementation is a clean implementation, not involve additional packages, and the image compose logger is used. It splits the disk operation and loopdev operation into 2 files, the disk operations is aimed not only used by the image generation but also be used by the ISO live installer.
